AIBU to think this is a racket? We have them from time to time and they always have a story about being out of prison, trying to make ends meet etc then turn very nasty when you don't buy anything. Is this a psychological ploy to make you afraid of turning them down?
I had one this evening and am now a bit paranoid that he's going to come back to give me more abuse, he was so unpleasant. I know it's unlikely.
