This is also for the guys,
First dinner date?
Pay the check. Not your half, not the tip, but the whole check, including a tip. And don’t be cheap, McDonald’s is not a date, it’s a snack option after months of being together. You’re trying to impress the lady, not make her tell her friends you’re a cheapskate. Also, always tip at least more than usual on the first date, like 22-23% instead of the usual 15-20%. You also want to be nice to the waiter/waitress, if you’re an ass to them, you’re probably an ass period, and no girl likes an ass.
