I was thinking about making a thread on this a while ago after an incident I had with one. I was waiting for my train home and having a cigarette outside the station, a homeless guy came up and started engaging me in conversation then asked for one which I gave him, after a while he asked if I had 80p I could give him which was what he needed for a train back to where he dossed,
apparently he was in Norwich because he got mugged and had to have gone to the hospital and if he couldn't get the train he'd need to walk 30 miles "home". I wasn't sure about his story but thought 80p wasn't much so gave it to him then he goes "I only need to try and find another fiver now"

I could obviously see where this was going but tried to remain casual, hurriedly finish my cigarette and get back in, but just before I did the cheeky bastard goes "I'm sure if you had that you'd give it to me wouldn't you mate" which I didn't know how to respond to
I didn't really wanna part with a fiver and I wasn't sure I believed his story but then I also thought it could be true and I'd feel bad for him if he had to walk 30 miles when really I could quite easily afford £5. In the end I gave him a couple of quid, said that was all the change I had, but I wasn't sure afterwards if I felt guilty or annoyed
Anyway that was all a bit long winded and I guess he wasn't your conventional street beggar, normally I don't give them money but if I have a spare 50p I might chuck it in their hat
