When I visited Canada, money annoyed me. Because in Japan, the size of coins is in order of the value of the coin, however, Canadian $ was different. And about Japanese coins, the number of the coin is very easy to see, however, Canadian coins are not so. It took for a while until I recognize which coin is which quicker.
In Japan, we usually pay money in the way to lose small coins as many as possible because it is troublesome to have a lot of same coins in the wallet. For example, if the things what I want to buy are totally ¥2,623, and if I don't have ¥623 exactly, I will pay ¥3,123 and will get one coin back as the change, so ¥500. We don't like having small coins like ¥1 or ¥5 or ¥10 so much. In Canada, I also tried to pay in such way, but, I couldn't since I haven't got used to their coins. I also thought that maybe I shouldn't pay in that way because we have to pay tips in Canada. When we first got to the hotel, a porter took our baggage, I thought that I should pay him tips, however, I didn't know the value of each coins yet and therefore couldn't do it well. I even couldn't use vending machines enough at that time! I was trying to put big paper money into it, however it didn't accept it. I was in a hurry, and didn't know what to do. While I was flustered in front of the vending machine, the porter came back and helped me! I was very ashamed at that time. I wanted to hand the porter tip for carrying our baggage, however, maybe I was acting weird because of getting strained and being ignorant.
After all, when I went to our room, I noticed that I did something wrong...I was shocked because I thought that I did some rude thing because of the ignorance and impatience. And I was a little bit shy to see his face whole the days at the hotel, lol.
Anyway, I learned that, in foreign countries, it is better to pay with big money and get big coins back as the change for tips :S However, the problem is, I will get small money that I can't use as tips a lot. So, I thought Japan is nice. However, it is just because we don't have to pay tips, and I've just got used to Japanese money :P
