When you're paying for drinks or a meal in restaurants or bars and you are handed the cheque, you should give the amount you have to pay and wait for the change. If you give the money and say "thank you" it will be treated as a "keep the change" type of tip. This also goes for taxis. The average tip is around 10-15% of the cheque. It is very impolite in Poland not to tip, because it means that you didn`t like the food or service (unless it was bad).

Saying "hello," "goodbye" and "thank you" in stores, restaurants, hotels and so on is normal.

Drinking in public places is illigal (the police can give you a ticket) and also inappropriate.

In Poland, ladies are always first and you refer to people older than you as Mr. or Ms.

Smoking at bus stops or on the street is noticed as being rude.
