If you travel often or just once in a while, you probably have the same questions as me when you go to a restaurant: is a tip expected? And if so, how much should I give?
You don’t want to be rude by giving not enough, but also don’t want to spend too much money or don’t want to be perceived as someone who brags.
This link: http://www.raileurope.com/international_tipping_guide.htm is a help to all of you who recognize this situation. On this page you will find the customs with regard to restaurant and taxi tips in Europe.
Have a great (international) networking day!
