Maybe it's just me, but one of my golf regulars makes a habit of hugging (very) young women like servers, and it's not to be friendly IMO. He's 73 divorced, and he's decided it's OK for him to frontal hug the 20 something girl that drives the beverage cart for tips at the golf course we play at. She plays along but I can't believe she appreciates it - he's old enough to be her grandfather. He does it with other young women as well, flirts with them at every opportunity (also seems out of line to me at his age). It seems totally inappropriate to me, but I am sure it would end our friendship if I called him on it no matter how carefully I word it - he has a very short fuse anyway.
Is it even my place to say anything, if the girls put up with it? Since it's always in a customer (him) to server (girls) situation, I can understand how they might choose to accept his hugs.
Or maybe I should just keep my nose out of it?
