Some women expect a man should pay for everything just for the pleasure of her company..
One time a woman asked me to go for a drink, chose an expensive cocktail bar and then a restaurant, was monosyllabic and grumpy throughout the entire date, and then when the bill came she just looked expectantly at me. I looked at her, she smiled and actually batted her eyelashes.
So I paid for my food and drink in cash, said goodnight, and left. Any woman that expects me to fawn over her because she's pretty and dull can find someone else. And she will, because men are often morons who think that paying means obligation.
However, she should have paid for the whole thing because she invited me out. At worst, she should have been willing to pay for herself.
Possibly, if I'd paid, she would have expected to sleep with me. I dunno.
I understand the desire to want to be treated. I understand that men usually earn more than women. But I can't understand why some women want to perpetuate the myth that they can be purchased.
