I did my bachelor study in Hong Kong. Afterwards, I worked for 2 years in Hong Kong, then headed over to Germany and finished my master degree there.
When I was studying in Germany back then, I went to a birthday celebration of a German friend. The party started in the evening before her birthday and lasted until the middle of the night.
Should you tip when eating out in a restaurant in Germany?
Yes! Most people do tip a bit.
So the second question would be: how much should you tip?
