I'd have to ask, what is it hurting? No harm, no foul in my book. Not like it's hampering the safety of the flight, nor hindering the time schedule of the flights, so I'd tell'm, in a nice way, to kindly place his lips upon your rear end.
Now, in this time of high level's of unemployment, I'd also be careful, because you are replaceable very easily too. Kind of a crappy situation.
