When I was mooching around Manchester centre the other week, I saw a filthy old tramp sat in a bus shelter holding out a coffee cup. Felt sorry for him and chucked a quid coin in only to hear a loud "plop" as it descended into a half-full cup of coffee. If looks could kill! Should really have bought him a replacement but I was too embarrassed...just muttered "sorry" and melted into the crowd!
