Paying and tipping
Credit cards are nearly always accepted in large restaurants nowadays but in more humble establishments hard cash is still the usual means of payment. If you want to pay by credit card, it is always advisable to ask before you order.
Paying for the meal is almost always done at your table with the waitress or waiter who served you. It is not necessary to tip 15%, because a 15% gratuity is included in the prices as a service fee (in addition to a 15% value added tax). It is nevertheless usual to leave a tip in restaurants, cafés and other places wher your bill is brought to your table. This is done by rounding the bill up. If a bill is under 10 euros you round the sum up to the next full mark or next but one - i.e. € 11,50 would be rounded up to € 12. If the bill comes to more than 10 euros you should allow 5% for a tip, rising to 10% in a more upmarket establishment.
Leaving the tip on the table after you have paid is unknown in Germany. Waiters and waitresses are accustomed to receiving their tip as part of the bill, not by looking for the tip on the table after you have left. If you let them give you your full change (and then leave a tip on the table) they will think that you are unhappy with their service. only if you are really dissatisfied with the quality of service that you have received should you not leave any tip at all - a token tip of a few cents will have the same effect.
Snacks
One of the most striking aspects about a German city is the number of kiosks (der Kiosk), sausage stalls (die Würstchenbude) or snack bars (der Imbiss, der Schnellimbiss) on each street corner. They are most well-known for offering Bratwurst - a fried or grilled sausage - or curried sausage (Currywurst). In Austria, you may come across "Steckerlfisch" - grilled fish on a stick. You can also get chips there (Pommes, Pommes frites), but don't be alarmed if you are offered mayonnaise along with tomato sauce to put on them!
Such kiosks and snack bars serve beer as well as soft drinks, and many will offer a very good ground coffee. The preference for coffee over tea in mainland Europe continues unabated. You may be offered tea in a café or restaurant, but most Germans drink it with lemon or just black. Iced tea is becoming increasingly popular as a summertime beverage.
