I took a friend to a gym class and we got out our apparatus and put our drinks to edge of the room. While we were doing this, a woman came along and put her bag on our stuff and then left, to get a drink presumably. Without thinking, I moved her bag and put it on the nearby bench and stood in position ready to start the class, when the woman came back in and gave me such a glare it nearly knocked me over. I just carried on with the class.
I know I was out of order for moving her things without an explanation. I don't want bad feelings. When I go to the class next, shall I just say I am sorry I moved your bag, I don't know why I did that. Or just leave it?
Minor issue but feedback appreciated.
Thanks
