How do you pay or who pays for the after hook up meal?

I was reading an article in a women’s magazine while waiting in a lobby the other day, and I read a contribution from one of the magazine readers on who pays after the hook up. She was complaining because the guy she hooked up with, not her boyfriend, or anything like that, spent the whole night in her apartment exploring every in of her body like an FBI forensic examiner, then when they went out for a late breakfast and the check came, she went to go to the powder room. When she came back, the check was still there. When the waitress came back to get it she inquired about the check. He said he assumed she would handle her part because he did not want to appear to be exercising rank on her by jumping to the conclusion she could not pay or wanted to bay herself, exercising her independence. She thought he could have at least handled breakfast after he help soil her sheets and probed nearly every orifice in her body. Should he, or was he right? I can’t determine if he was just cheap figuring he already was given the keys to the castle why make another payment, of he really did not know. Back in the day the protocol of courting was way more clear, a guy knew what he was supposed to pay for, when to open the door, hold the chair, etc. these days there are no rules; everything is the wild, wild west. These days what is your expectation when a person meets a guy and between date one and date five they do the horizontal mambo, who should, or how should the after hook up meal be handled?
