I hate that shit. Most of the people at my gym are scums. They are more worried about how their under armor clothing looks on them, then about washing their hands.
I see it all the time, take a piss, take a shit, don't wash hand. Nasty fuckers.
Another thing that really ticks me off, is that 90% of the cardio equipment is never cleaned by the person who just used it. They just walk away............lazy fucks!
