I feel a little bad for your dates. No one likes to be used for money. Maybe I'm just a little too feminist, but I don't think it's fair that men are expected to pay for all the dates, or all of the date, and I don't think it's fair that some women use men for a free meal ticket. Now, if you genuinely were on a date with him and looking for an honest connection or hook up, then maybe okay? Still, ramen diners cost under a dollar and while not nutritious in the least, at least no one is being used.
Im honestly not sure who to feel bad for - you or your dates. I can relate waiting to getting paid and not really having food in the house, but to use dates for food is sad and hurtful to your date.
Mind you, Ive never been on Tinder, and not sure 100% what that is other than guessing its a dating app (site?)
