When I buy something and give the exact change, the cashier will almost always say "[something] hǎo", but I'm not sure what [something] is.
Question: What are people saying when I buy something using the exact change?
It sounds like "gèng hǎo" or "zhàng hǎo" or something along these lines. It might possibly be 更好, or it could be something else. I'm not sure.
