I'm going to ask to use a machine at the gym that someone else is already using.
Really? Is it your favorite machine?
No, that's the only one I want to use.
If you could wait until they are finished it would be the most proper thing to do, otherwise they could get angry with you and even yell at you. I am fearing for your safety, that's all.
I just want to get in that machine. It's not too much to ask for.
But look at it this way too, if it was you and someone asked to give it up would you? It's commendable to put yourself in other's position at times just to avoid a confrontation of sorts that could even land someone in jail if the scene escalates. And just over a gym equipment. Would you want that for yourself?
