1. Poor form with heavy weight!!!!!!
2. People who don't put equipment away. (Saw an older man who likes to bench with the bar and a 10 on each side and some kid left 225 on the straight bar, had to go help the man take it off.)
3. People who do like 10+ sets on the preacher curl, bench, squat rack etc. And walk around the entire Gym between sets.
I do that - go for a minute walk between sets - good technique for consistent rest periods if you ask me.
