Max well-
I agree with you 100% but the question is- where do you draw the line?
My sister went out with a guy who abruptly stood up and said, “if we leave now, I can still catch second seder”. How holy is that?
Would you say that once the guy realises she’s not for him he has to leave right away? Is he allowed to drive her home or does he have to pay for a taxi for her?
Hopefully you agree that he should finish the date like a mentch and drive her home. For some people the date isn’t finished until he takes her out a second time so it isn’t too depressing.
Going out more than 2 or 3 times when one knows it’s not happening is, in my opinion, Gneivas Daas. I don’t feel that way about a second date.
There was a story going around yeshiva while I was dating about a guy who opened the car door for the girl after the date for the ride home. The girl reached in and opened the button to the back door. She explained to the guy that her Rebbetzin said she can’t sit in the front seat if she knows she’s going to say no. The guy said that his Rebbe said he can’t let the girl in the car if he knows he’s going to say no.
