Reading town centre has a number of beggars and I *used* to sometimes give spare change to them, but I always had a nagging doubt in the back of my mind that said they were just chancers and were just using the money for a £10 bag of smack or whatever.
Then walking home one night I saw a young lad who was a little bit drunk, stop by one of Readings well known beggars and pull a couple of quid in coins out of his pocket. Handed it over with a friendly "Here ya go mate, if I had more I'd give it to ya".
To which the beggar looked at him in disgust and said "What? You want it back then?".
Not "Thanks mate" or "every little bit appreciated".
Since then I've not handed a penny over to any of them, as far as I'm concerned they are all parasite scumbags who deserve to starve.
