I was not going to watch a strangers's stuff for him while he went to the bathroom? This was in an airport.
Why wouldn't you keep an eye on someones bag?
Because I don't trust the guy.
Is there a reason why you don't trust them? Why not just watch their bag if it takes little effort from you?
I have barely any time left before this flight and I have to get on board.
Well if you feel like you didn't have the time to watch his bag because they had to leave why not just tell them that? I'm sure they would have understood.
