the only problem with that prime is that sure, I can go up to a 120 pound kid sitting on a bench doing nothing, and get all aggressive on him, sure that will work. but I also have to do it to the 290 pound steroid dripping yoked out tuff guy doing the same thing?
and I'm not going to do that at my age, because what if he gets pissed and all crazy, and gets in my face? then I have problems. I have always thought like that, its easy to be tuff on a little guy, but what if its a big stud?? not a good percentage move in my thinking. so I don't get into anyones business. of course I will
nicely but strongly ask the little weasel if he's almost finished, but when they see old judo choke, dripping sweat from his bald head, they normally just leave.
actually the last big guy I got into his face was CSWOLE. we barked at each other for a minute or so, and we both backed down at the same time. we were instant friends after that moment . miss that poyope eating chicken fellow 
This is why you need to be firm, but polite. Also this is where being a senior citizen comes in handy. Only an insane person would physically threaten an old man in a public setting.
Anyway, my experience has been that guys who look like they workout, actually workout and don't wile away their time hogging equipment by spending time on their phones.
It's funny how things work. That you and CSWOLE became instant friends after a dust-up isn't at all unusual.
