Dash,
I have witnessed the same behavior over the last SEVERAL trips in 2013. First it was on the West End following the One Love bus. Our last trip in December it was on the beach as well. After I refused to buy the begging started and a drunk tourist who I was talking to handed them a baggie loaded with cash. It was all of his money and I pointed it out to him. He grabbed it back, peeled off $200J and told them to beat it. I'm sure this happens often and now these young men have turned into opportunist.
