Dannychoo talked about tipping in Japan compared with tips in the USA a while ago. In Japan you don’t need to tip, it’s easy compared with the United States system where you have to be always calculating tips. They should include the calculation in the receipt! I hate that even when you pay with credit card you have to be calculating the tip.
In Japan the “tip” is supposed to be included in the price. Once, I forgot one yen from the change, and when I was crossing the street I saw the guy from the shop following me to give me my yen! I learned the lesson. You could think that not having tips would make the costumer service worse than in other places, but it’s just the contrary. Costumer service in Japan is the best in the world. They treat you like a king, they are always doing reverences to you, smily faces everywhere, they always ask you about everything before proceeding, they use honorific language to talk to clients etc. The best customer service and no tips, I love it 🙂
