So I was doing lat pulldowns. After my first set this dude comes up and asks if we can share the machine, take turns. I said ok. But then he immediately tries to switch the bar attachment. I stopped him and told him wait until I finish my 3 sets, otherwise it’s too much rest for me in between. He gives me a “whatever” look and still goes to change it, so I grabbed the bar and said no, it’s my call since I was already using it. He gets annoyed, calls a trainer over. By then I was done anyway, but the trainer sides with him and says I’m supposed to let people work in, clean the machine each time, then let the other guy switch the bar, do his set, clean it again, etc. Basically meaning I’d be waiting 2–3 minutes between every set. Trainer even told me if I don’t like it I should come at odd hours or go to another gym. This isn’t some tiny neighborhood gym either, it’s a big premium gym with 3 floors. Later the guy was calling his friends over, pointing fingers at me for an hour, but no actual fight broke out. So was I wrong here? Or is this normal gym etiquette and I’m just overreacting?
