Of course the man is expected to pay the tab. Of course there is the exception of his birthday or the fact that the lady simply wants to treat him to dinner once in a while. But for the most part it is courteous and chivalrous for the man to pay the tab, or hold the door for a woman.
Spoken like a true gold digger.
That's the difference in men's and women's attitudes. You rarely see guys running around trying to find a women to pay the bills. Even if a guy makes low pay at a crummy job, you never see a guy trying to mooch as many freebies off a partner or date. Usually, guys are the ones who work, get a pay cheque, and don't expect or feel entitled to have someone else pay their tab.
It's not a matter of "being a man" or "manning up". It's just the way men and women think.
Whether people like it or not, guys put more effort into things in general (career, expected to all the shit like shoveling snow, building decks, checking the car because something's wonky about it, mounting TVs onto walls, etc.... It's not like all guys are expert in doing this stuff. But they still put in the effort to at least give it a shot before calling a professional contractor). It would be great in the year 2016, if women didn't treat modern day like like it's 100 years ago when the guys went to work and the women stayed home.
Nowadays, both people usually go through the daily grind of going to work and taking care of the kids. The guy is expected to do most of the physical work, so it would be great if some women would at least toss in a few bucks, as opposed to treating the guy like Mr. Bottomless Pockets. Most women work too now.
