Hi I’m a Korean who loves to watch NBA. I travelled for a week last month, I encountered a situation to get a receipt that tip price is writtenmany times. Once, i got receipt with $10 tip (20%), all I had were $20 bills. I asked a staff if i can change $20 bill to 2 $10 bills. Of course, I said that it was to give the tip.

She kindly changed the bill, but i cant shake the thought wether i was rude or not.

How do u guys think about it?
