5 people, bill came out to be $78.

I had zero cash, so I was going to put my card down and take the cash.

But one of the other people had a 100 bill that he put down and he took the cash that was there.

So at this point, I put down my card and took the 100 bill, and when it came back, I wrote down 120 after tips, because I thought I needed to pay for my food (since I just took 100 from the pool).

So this ended up being a 50% tip for the restaurant. And now I'm thinking the guy who put down the 100 prob expects me to pay him back a 20 at some point.

It was an Asian owned restaurant, so I don't care.

you just had to owe the guy.

after I took the 100 and put down my card, I said something like, "so do i owe guys name 20 now?" and they were like no just put down your card.

And I was still confused about that when I tipped, and I didn't want to end up only putting 100 on my card because that's like I didn't pay anything.

Mr. High-roller had already baked in a 25% tip when he threw the $100 down. OP then unnecessarily added another 20% tip on top of that. Thus, OP should be out the cost of his own meal, the pro-rata cost of the 25% tip, and 100% of the cost of the 20% tip he added of his own volition.

To resolve the situation, OP could either accept that he had acted presumptuously by assuming he owed nothing to $100 bill guy and graciously absorb the "idiot tax" by giving a full $20 to him, or OP could potentially explain to $100 bill guy that he had added $20 on top for the meal in good faith, assuming that $100 bill guy was "square" at that moment and was owed nothing, but since $100 bill guy doesn't feel square that they should split the extra $20 that was paid, $10 each.
