I am happy to say that nothing bothers me at my new gym, and I have been going there for over a year now I think.
I haven't had any of the typical negative gym experiences I always hear about.
In fact, for whatever reason it seems people at my gym are even more polite than the average person I run into anywhere else.
My old gym was incredibly crowded, but everyone was pretty cool there and didn't hog the equipment or anything like that. People were always cool about working in and wouldn't move your stuff if you were only gone for a short time (which is all you need if you are drinking from the fountain or something like that).
So even when I had tons of people around at my old place, it still wasn't bad at all. Sure, you would get the occasional weight dropper or loud guy, but it was never enough to cause a scene.
Both gyms are in the same town that isn't all that big, so maybe I am just fortunate to live in an area with mostly respectful people.
