When traveling in Germany and in some other European countries it is important to carry extra change with you. You will need the change to pay to use the restroom. It usually costs anywhere between 0.30 Euro cent - 0.50 Euro cent. Places where you normally do not have to pay include McDonalds, most restaurants if you eat at them, and a few retail shops if they have a public WC. You even have to pay at most malls to use the restroom, usually around 0.30 Euro cent. Most gas stations cost 0.50 Euro cent but will give you a ticket you can use at the station to buy something. There are a few exceptions for everyone. Handicap people usually do not have to pay and if you need to change your baby's diaper you can usually do that for free. However, not all changing rooms have a toilet, so you may still have to pay for yourself to go. On the positive side, the restrooms in Germany are usually really clean.
