Sometimes it is very difficult to make the call when you're confronted by a suspected scammer. Today I was stopped on the street by someone asking for change for a taxi to hospital. 'Here we go...' I thought, until he put his right arm in front of me and showed me a rather gruesome open wound and told me that he'd come off his bike. This took my back somewhat, so I fished a couple of quid out of my pocket and was on my way as soon as I could. Perhaps I should have offered to phone an ambulance, but assuming it is a scam it is quite effective. This wasn't in ED, It was the north side of London Bridge, but I wondered if anyone else has encountered this or knows of a website which keeps tabs on this sort of thing. Is it a real wound? Does he aggravate it every morning before ?work'?
