Here's an interesting article about trainers and gyms being selective about who they work with or who joins. I think there's a lot of applicability to martial arts programs, too. Your club may not be the right fit for everyone, and maybe by being selective up front, you can be more likely to ensure a good outcome in those who do come to your club.
"Let me have a think about it."
"I would like to do a tour."
"Can I come in and chat with you about it all?"
"I want to try out a few classes before I commit to anything."
These are all questions and comments that we, as coaches and business people, hear on the phone and via e-mail inquiries. Frequently, these are precursors to a potential customer booking an appointment with us and seeing if what we do is a good fit. A lot of the time people say these things because they are unsure of what useful things to ask and how to progress the situation from curiosity to action.
At my gym, we work hard to help people make an informed decision around whether this is a good option for them based on their needs and expectations. If you own a facility and you are not helping people figure out if what you do is a good fit for them, then you are doing a pretty crappy job of helping people out. It should be noted that clients of ours have occasionally suggested the initial enquiry was difficult for them in terms of the questions asked and the answers sought by me and my team. This for a good reason. You - meaning, you trainers - cannot work with everyone, and if the culture of your facility is important to you, you will be selective about who you work with.
