Just see how annoyed people look when tony gives them the awkward rapehug, it's like their mom showed up to tidy up their hair in front of the school, same reaction. Tony is the one being inappropriate but for that kind of money, and working with friends, and time with their families yada yada... They could at least put a little more effort in showing happiness for fuck sake
