Genuine question here- Why do the girls feel so privileged on a date and never put their hands in pocket

I had faced the same issue over my previous dates that they never put their hands in purse, even if they are ordering themselves or the waiter just gave them the bill in their hands or for the cabs

I mean, how could it be possible if the waiter had given me the bill, out of self respect I would always pay the bill

In nutshell, going on a date costs a minimum of 3-4K for a guy but a girl has no expenses and can show endless tantrums

Does this happen with other guys as well and girls what are your views on it?
