Got 'em

If he has 50 and I have 200 I will pay. Because if I had 50 and he had 200 I would offer to pay half but I would hope he is a gentlemen and would offer to pay for all of it because if he offered to pay half when I had 200 I would say keep your money I got this.

For me the person to pay is the one who didn't pay last time. I have this with friends, family anyone who'd close to me. But it is an exception if you explicitly got invited stating they would take you out. Then the person inviting pays.

I think it's the one who suggests who pays.

I pay for myself unless I'm on the first few dates (then I insist and insist on paying) or it's a movie I want to see with a few specific friends... and then it's "I'll buy the tickets, you smoke me out and drive so I can get fucked up".

Split the check always split the check
