I have seen the put the two guys together and let them hurt each other, and see if they learn anything.
I have also seen that they only work with a senior person who can control the situation.
I have also seen people just block hard enough that everytime the reach out strong they get hurt or they end up on the floor as their energy is used against them. But this usually takes someone with more skill set as above.
I even talk to them and ask them to play nice and work with others.
When it does not work we ask them to leave.

I do have a story where everyone thought I was that bruiser. I was at a TKD open training on a Saturday. My friend had stopped training in TKD at Red Belt Black Stripe but had continued in other arts. The Senior Master ahd asked him to at least get his Black Belt and then he could "retire" as he called it. So, I went along as a lo color belt in Modern Arnis and was concerned about the differences. I was introduced the most of the seniors, but one came in from warming up elsewhere and took over to start the training.
As I was wearing my Rank from Modern Arnis, I knew how many belts up it was, so I lined up with the same number of ranks in the TKD system. I also lined up junior to all those in that rank. The 4th leading and starting the class was upset I was not properly lined up. (* Note: Everyone was wearing traditional White top and bottom, I was wearing Red Bottom and White Top. *) So, as not to cause a scene I lined up Junior with my "Color" on my hip. I looked at it like a good thing, hoping I could work with seniors and learn more.
They started with Forms. Opps. I knew nothing about that systems forms. I was soon relagated back to the White Belts to learn the first form. (* Note: Each time I tried to explain that I was from a different system and as a friend of a guest invited by the Senior that I did not know. Most ignored me and just gave instructions. So I listend and tried my Best. Sometimes doing OK, others times I coudl hear the laughter from those who were wondering about the "Color" on my hip.
After this we went to one and three steps. (* This was back in the mid-80's *) At first it was prescribed what we were to do, strike this way and then counter that way. So, I did it as told. Later, we were told to do what we knew to allow us to practice what we wanted. So, I started steping 45 degrees, and trapping and parrying versus blocks. One of the Black Belts saw this and moved me up to be with those that had the same color as me. (* I think the BB had been out of the room earlier and missed all the above as he was training in a separate room *).
The guy I was put with, was not going to have this "person" who could not do simple forms show up now and show him up. So, he started hitting real hard. I asked him if I could block his counters? He said no. So, when it was my turn I hit him back. This caused him to take it up a level. Soon it was just close to a fight. It might have been on his side, but I was still using control and not looking to permanent damage just looking to make sure it was felt.
We rotated people to work with. The new guy was not going to be shown up either and when he added in a sweep on the GYM floor and took me to the ground, I asked if throws were allowed. He said anything we knew was allowed. So, I did a throw back to him. A nice arm bar take down no real force to hurt him. He came back with a harder sweep. I then worked on an elbow strike to the head. I did not make contact. He came back even harder. I then threw him to the floor. He did not know how to fall. I reached down apologized and told him I was sorry and asked if he needed help. Boy was that the wrong thing to do.
So, one of the Black Belts moved me up a color range. So I was now sparring with people of a much higher color. These guys did not want anything to do with me. As always I was a guest and let them go first. I wanted to see what was expected. The first guy hit me so hard in the head, it hurt. I just smiled. I dropped him with a arm/leg throw/sweep. The same Black Belt then moved me to a different person. This guy came at me hard. I put up my hands to block and defend myself. He walked into my elbow. I was moved again. This guy and I exchanged punches and kicks. He said no throws.
At this time I was moved again to the rank just under Black. The Red Belt - Black Stripe. These guys had more control, but were looking to make sure I knew they were ready for BB and knew more than I. It was a little blurry here it started to repeat much of what happend before. We started Continuous sparring at this point. Whole class, not rank associated.
The Black Belt moved me up with him. I was then to do continuous sparring with them. The younger guy that kept moving me up started out and he was good, and it was fun to spar him but we were exchanging and the tempo was getting faster and harder. A Thrid Degree came over and moved me up to the second degrees. The first guy started hard and it was lots of more fun of hitting each other. In there similar story happened and we got separated. I was then to spar with a older 2nd degree. The man asked me to not hit him in the head. He also said he did not want to be hit hard. That we would work on our timing and control. I siad yes Sir. I did not hit him in the head. I made sure if contact was made it was very light. He enjoyed the sparring as did I.
I then was able to spar with the Third Degree, but he just played with me. He was able to pick his spots and hit on his desire. He said I would control the timing and the level of contact. If I did get to hard, I would apologize, and here the too hard was not 50% of earlier. It was just not what I had wanted. He would smile and acknowledge that I was recognizing my mistake. When we were done, he smiled and put his hand around me and said he did not expect to like me or enjoy working with me and watching me learn. He had seen me "work my way" through the students there, and he thought I was a bully there to hurt others. But when he saw me not hit the 2nd degree when he asked me he was going to give me a chance without "teaching me a lesson."
He did teach me and help that day. But it was not my intent to have ended up where I did when I started that day.
Thanks
