The only annoyance I get at my gym usually is when this group of four or five people come in to lift and hog two of the three power racks for literally an hour, over half of which is standing around. I get rest periods, but this is obscene. And one of them is a small fat 'power lifer'. I dislike those ones the most.  /gym rant. mainly based that my gym is small so five people in the weights room clogs it up pretty bad with the amount of space.
