They have that rule at gym as well....but like all the others, it is not enforced.
It's funny, this one time, this fucking old tool comes up to me and tells me to not slam my weights. The irony is, ANYONE who knows me, or has trained with me knows, I don't do that shit. So, I told him, hey jag off, why don't you go bother someone else and leave me alone? Who the fuck are you, the weight police? The fucking nerve!
Funny thing shit is, I called him on being a hypocrite....why? Well, there's a rule against wearing jeans to train. Guess what, he wears some...ALWAYS. That shut him up......
I'm usually calm and nice, but for some fucking reason, this asshole just made me go off. Fucking nerve! If I had done something wrong, I would have apologized....that's the way I am.
