I was in Edinburgh in a hotel a few years ago. I looked out my room window and across the road was a young guy sitting up against the wall of a bank, with a blanket round him, and his head bowed low, staring at the ground.
He looked homeless, very sad, and rather desperate. People were dropping money into his blanket.
I had my hotel breakfast, and 30 minutes or so later walked out the front door of the hotel.
He was still there, but as I crossed the road he happened to stand up and remove his blanket.
Underneath he was pretty well dressed, with Nike trainers, and under his arm were some student notebooks.
He then got up and (I assume) went off to his college or university where he was a student.
Obviously his "homeless look" was a con and he was just scamming people who walked past, trying to make a few pounds.
But I got quite annoyed that he had been conning all these people who had dropped money into his blanket.
Obviously I am not saying all homeless people are like this, or that anyone begging is conning people, but it does pay to be careful who you give your help to.
