Have you ever caught a thief redhanded?

Yes, we have. We were eating in McDonalds and we noticed a man acting strange. My boyfriend had watched him enter the restaurant on his own, but he went upstairs and sat at a table immediately without ordering food. A woman was sitting in front of him with her bag on the floor and we noticed that he was slowly pulling at the bag so it was moving towards him. We both yelled at the lady and told her the bag had fallen over, then I pointed at the man so she knew the real truth. He immediately got up, but instead of leaving he actually went to the next floor which was really strange. We were done eating, so we went downstairs and told the manager of the would be thief. As far as we know she phoned the police immediately and he didn't manage to steal from anyone that day because of us.
