They can have fun and making joke out of a old man, but the thing is...they never even pay the old man. They make use of this poor old man to entertain them. At least a few dollars if they think the old man is not providing a good service to them but the fact is...they were being entertained, that could be their intention in the first place. You can see how happy they were in the video. This video clip should be air around the world especially England and see how their people react.
