Sometimes it can be interesting. I was approached, years ago, near Grand Central Station in NY. Fairly well dressed guy, with English accent. As I am English, he may have heard me speak. I got a very well crafted tale of woe, I am a doctor, lost my wallet, etc. He would give me no of hospital to ring etc. I was sure it was a scam, but very impressive. We talked for 10 mins. Eventually, I said that I did not believe him, but I would give him $10, as I thought his performance was so good. He went away happy!
