That might happen, but how often?

(of course the first date should be in a public place).

IMO it's absurd pressing an hypothetical on someone and expecting something in return ("I risked my life, so you should pay"). My example make the same absurd statement: do you think it makes sense? Of course it doesn't; it's a fallacy.

BTW, many women keep dating. Just some women do not anymore and, if that's for the reasons you expose, it's better this way.
