How much is it to go to the toilet in Germany?

This is not normal. Generally speaking, if you charge 20 or 50 Euro cents, I have hardly seen 1 Euro in Germany. If there is, it is too high. This coin-operated form can only appear in gas station toilets or some railway station toilets;

In restaurants and some train station toilets, some people collect consumption outside. Usually there is a plate in front of him with some coins in it. You can depend on the situation. Generally, Berlin, Munich, Hamburg and other big cities start from 50 Euro cents. No matter what you want, as long as you are happy, no one will stop you. If you are not happy, you can spend 50 euro cents. He can't help it if you are unhappy. In some cities in East Germany and some small and medium-sized cities in West Germany, 20-50 Euro cents is generally enough.

Your father's 1 euro is really hard to get. You'd better add his position and specific situation so that we can analyze it in detail ~ ~
