I happen to not only work in, but run, a restaurant in Germany. While I haven't got the time to quickly draw up a concise dictionary, if you have any questions don't hesitate to get in touch.
What area of Germany will you be working in? What type of restaurant?
I wanted to know if you allowed students to come and work for you?
I might be interested, but we are a small restaurant and can't pay a full-time wage. I'm also concerned about the legal, i.e. immigration/work permit, side of things. What nationality are you?
