Tipping in Europe is not as automatic and as generous as it is in the United States, and in many countries, they are not expected at all. At restaurants, check the menu to see if service is included; if it is not, a tip of 5-10% is normal. In most places, 10% is a big tip. Tipping is an issue only at restaurants that have waiters and waitresses. If you order your food at a counter (in a pub, for example), you are not expected to tip.

Please respect people, the environment, and the culture.

Please keep your voice low when talking in public and on the phone. In many countries in Europe talking loud in public is considered rude.

Please do not litter and dispose of your garbage in a designated place or container. Most countries in Europe separate trash. Please dispose of your garbage in the correct containers.
