This. I worked at a golf course for a summer and all of the other employees were attractive young women and literally every other guy who came into the pro shop attempted to flirt with them. And most of them were older and married and probably didn't intend to seem sleazy, but it didn't take very long for the sheer volume of it to gross me out.

To play devil's advocate here: isn't there a difference between harmless flirtation and actually attempting to initiate a sexual relationship? Maybe these older, married men miss the days of their youth when they could be around pretty, young women and flirt with them (and more...), and in their current lives they don't have that any more because they're in a boring, monogamous marriage to someone who's not so young and pretty any more and maybe their marriage is rather unhappy too, and their flirtation is just a way to make themselves feel happy, even if they really know that these young women have zero interest in actually having any kind of physical relationship with them. Maybe they just like the interaction, and it serves as a happy distraction to their otherwise unhappy existence.
