As a former male server I experienced women hitting on me in ways that I thought only men did and it didn't feel great at all. I'm sure there will be guys out there saying that's a good problem to have, but it really isn't. Especially if you have a wife already.
To describe it succinctly I and many others are a captive audience in these agreements to labor/income. I'm not necessarily attracted to you just because you are in my vicinity.
