well... I was starting my chest day once with incline barbell press. i had 185 on the bar to get started... and i'm sitting on the bench and i lean back, get my grip, lift it off the bar and i almost tipped over 'cause one side was way light... i throw the bar back on the rack and get up to see what the problem was.. and this dipshit on the leg press behid me had taken one of the 25's OFF MY BAR... while i was on the bench about to hit a set. I was seriously dumbfounded man. he freaked out, apologized up and down.. fuck etiquette man, ain't some of this common sense?
