Is AUTHOR wrong in the post ? POST : I've only started to hit the gym recently, so I don't know much about gym culture (nor am I familoar with the terminology so please correct my mistakes).

The other day, I was doing my usual routine of pullups with a 1minute break between sets, and this guy insist that we should "share" the machine. He gets to do his sets when Im resting and vice versa.

And I said no; not only was he rude in suggesting we do so, but I have a strict break interval and didn't want it ruined.

AITA for not sharing the machine?
