My gym is actually quite a good standard. I mean obviously there are dudes doing the usual stupid shit like quarter squats, half reps on the bench etc., but the standard is probably the highest out of every gym I've been in.
The reason being that 80% of the dudes lifting in the free weights area are on the uni rugby team, so they know their shit. At first it was a bit of a pain in the arse because there's so many of them and they seem to take the place over (weights room's pretty small) but they're actually really friendly and let you work in. It's a case of everyone respecting everyone else who works hard.
I did have one guy (not rugby team) who kept walking into my rack just as I was about to squat to fix his hair. Did it four times.
Surprisingly, the most annoying people are the Scottish Powerlifting Federation (I think that's what they call themselves). The sense of entitlement among those old dicks is unreal, and they have no qualms monopolising the equipment and getting all arsey when someone else wants to work in. You just can't justify using a rack for 2 hours. Dicks. I don't care if you used to have the Scottish record, now you're just an old unfriendly fat dude.
