oh op, that really sucks ;_; glad you're ok now though.
I have just had the whole "I'm eating right now" happen to me, but nothing crazy.
For ym friend though, it was different. She was running to the bathroom and people followed her into the bathroom and insisted on taking a picture. She's like "OMG I HAVE TO GO TO THE BATHROOM! PLEASE WAIT!" they waited right outside of the stall she was in. I had to help her get out of her cosplay during this whole incident.
some people just DON'T get it =[
