<prompt> Human: I parked for 9 hours and 57 minutes as evidenced by a receipt I received with the transaction. Their pricing structure is under 10 hours, 17, over 10 hours, 38. I was charged 38.x200B;When I asked them about it, they said oh yeah, we round up, and said I could talk to the manager on Monday; I wont be here Monday, I live 5 hours away and Im here for the weekend.x200B;Shall I do a credit chargeback and provide the receipt and picture of their pricing sign to my credit card company? I know 21 isnt a big deal, but theyre stealing it from me and Im not okay with that.  <response>: 21 IS a big deal. How many hours of your life get used to earn that 21? I would never accept Oh, we round your final tab up. Either you round down or give me the EXACT total.
