Toilet trivia:European public toilets are charged

If you don't say you may not know, many European countries such as the United Kingdom, the Netherlands, Germany and other places use public toilets to pay, even if you enter a fast food restaurant or shopping mall, usually an employee sitting at the door to collect money.

This is because Western culture believes that this is a kind of service, and the toilet supplies should be regularly maintained, repaired and cleaned, just as if you hired a person to clean the home, the same reason.

So when you travel, don't forget to bring more change, otherwise the toilet can only be used.
