The Scene: Supermarket checkout
Young boy at till serving a little old lady who is chatting away endlessly whilst he is very politely responding to her. After about 10 minutes of this she finally leaves and I get to the checkout
J: if there was an award for patience you'd definitely get it, still she was very sweet
Boy: well you'd think so wouldn't you but last week she threatened to stab someone in the cafe with a pair of scissors because they were talking on a mobile phone and it annoyed her apparently.
J: oh my god you're kidding
Boy: no not at all, I was surprised to see her here again, I thought she'd been banned!
