I only had this happen when I would go to group and some guy would ask me to watch his backpack. It didn’t really bother me.

Sort of unrelated but kind of related, at work a few months ago a girl got a call from her boyfriend when we were supposed to be working and she made me be watch-out for the manager. I don’t care if she trusted me I don’t want to get in trouble. She did finally end up getting in trouble for being on her phone though.
