Man I hate people that do that! (and I see it a lot!)
This is when I saw something I couldn't believe. The bar was loaded with a dime on each end and some guy was doing barbell curls in the damn power rack! Not to be a dick, I waited until he finished what seemed to be ten sets and then made my way over to the rack.
That's total BS in not allowing deads! How about the music at most of these places bothering people? The backstreet boys or other bubble-gum songs that most gyms play aren't exactly what I call lifting music.
He then informed me that they didn't allow deadlifts in this gym. Now I was getting a little pissed. He told me that the weights hitting the floor are too loud and it bothers the other members. So I told him the sound of the treadmills and Stairmaster motors are too loud and that bothers me. Why doesn't he go over and tell the other patrons to get off the machines?
