Eh, bro......
I know what you're trying to argue and I totally understand it, but as a man I think you gotta be above that and just pay the fucking tab.
I'm not going to get in to the "equality" argument here as it's just pointless. Being a man, I think it's just your prerogative to pay, regardless of the circumstances. If it's a long term relationship, sure it's understood that she will reciprocate, but in general I think the man pays.
I always do, but keep in mind that I only take women out to dinner that I see as longterm potential.
