Just take the bill to the office to change the invoice … and their office is always next to the bathroom … Just ask the waiter where the office is … And Daimei likes to change money from you, such as 62 yuan, and only give the invoice to 60 yuan … I thought he rounded it off … once in 87 yuan, he only gave it to 80 yuan … So you must see the price clearly … Don't miss a penny … He always thought there was no 1 yuan.
