First time was kind of weird, self conscious and all.
Since then, I just go and do my thing; care less about what others think. Still avoiding to hog the equipment and be polite and all that.
Also I learned more technique so I get fewer injuries, and I go slower on increasing the weights from week to week.
In my case, people just don’t seem to care, i mean they are polite and all but everyone kind of do their own thing. After a week or two, i realized that and became comfortable..
