well i have a few things that annoy me in perticular in my gym im curious to see what gets on everyone else's nerves. The first thing that annoys me most is people who wear denim pants to the gym (not to sure why on this one, lol it kind of makes then look unseriously how can u train in denim pants) then bad music, and last is people who go to the gym and then mess around on the machines (obviously messing around, not just inexperienced) I figure with a thread like this everyone can post what they hate most, and it would lead to everyone having better "gym etiquette"
