EVERYone can be asked to leave, and if there’s refusal, EVERYone can be “made” to do so.
You’re not fighting a guy, you are removing him.
If you are large, very strong and well versed in control tactics, it’s a job very much that bears no resemblance to facing off, one-on-one, against a guy in a controlled sporting environment.
A top UFC athlete (whom I won’t name) visited an establishment in which I once worked. If he had behaved unacceptably, he would have been removed, one way or the other. Just another incident. Thankfully he was a polite and friendly fellow.
I’ll tell you this. Forcibly removing, say, a Brian Shaw-type, would be considerably more challenging than the gentleman you present.
