I've seen quite a few big benches. There are guys who come in, seem to only train bench and maybe do some curls, but bench way over 100kg. I've seen some of that ilk bench 140.
But squat and deadlift are mostly pretty poor. I've never seen serious squatting and deadlifting in my gym at home. There are a fair few powerlifters at my uni gym, but to be honest a lot of them are quite mediocre too. I regularly see over 2xbw squats, and 200+kg deadlifts, but they are the better ones. Now, there are a few beasts, but they are very much the exceptions.
