I literally have guys standing in line to talk to me! ( airline ticket agent)
I get hit on and flirted with quite a bit. I do think most of it is just in good fun. Kind of a captive audience for guys traveling alone on business and such. Old, young, tall, short, fat thin... I don't mind as long as they keep it light and keep it clean. Breaks up the day, good practice, and most of them are pretty nice.
Pilots .... On the other hand need watching. They (even some of the married ones) will say anything to try and get over. Lol
