I bend over backwards to accommodate people in my gym. I go out of my way to insure that there is a level of comfort for ALL people whether they are in MY program or any of the other ones that exists at my place.
I reserve Saturday mornings, VERY early Saturday morning to train with a crew of people that I know won't ask a lot of questions so I can be an athlete for a few hours without needing to fill the coaching role. In doing so, I turn into another kind of person. Not the normal nice person, but a competitor! Which also means I have low tolerances for poor performances from any aspect of living.
Most of the time, I will allow a certain amounts of narcissism from the very prevalent "Entitled" community and let them live and breath without much dialog from me. "Teach them for they do not know" is the credo. BUT! When basic manners are sacrificed compounded with my lack of "niceness" The gates of Hades are opened.
I know it is ONLY chalk in a bowl. I also know that at the end of today, it doesn't amount to two shekels and a rupee. But I will NOT put up with someone coming into MY HOUSE and telling me what they are going to take, or do.
You might want to consider the scene from "A Few Good Men" when Col. Nathan R. Jessup told the young Danny Kaffee that he would have to "ask nicely" Because, "You have to ask me nicely. You see, Danny, I can deal with the bullets and the bombs and the blood. I don't want money and I don't want medals. What I do want is for you to stand there in that faggoty white uniform and with your Harvard mouth extend me some fucking courtesy! You gotta ask me nicely."
Take note Entitled One's... You better start asking NICELY.
