In an ideal world...sure. In this one? Better safe than sorry.
Those who are saying bring a friend...if I had a "friend" who kept asking me to stand around for several hours and wait for him/her to do a shoot, I'd start feeling used if I wasn't being paid. Given that some of these are cases of the model getting prints for time, the model may not be able to hire a friend if the model gets, say, 10 hours per week of work. It ain't that simple.
