Personally, he could have ask an aide of his team, to have done this privately. He does looks a bit out of touch, very embarrassing for all involved.
I agree...definitely looked out of touch and like the massa handing out some coins.
Candidates should all know enough to tell the person to see a campaign aide designated for this purpose.
Reminds me of the scene in 'Trading Places' where the Dukes hand out their Christmas bonus of five dollars...."Five dollars.....maybe I'll go to the movies.....by myself."
