"Paying the waitress/barmaid" Krakow Warnings Or Dangers Tip by SooBrand
Krakow Warnings and Dangers: 108 reviews and 94 photos
In a bar, we had a drink each for a total cost of about 12 Zl. I paid with a 20 and the barmaid thanked me and vanished into the crowd - no change.
Initially I thought I had been ripped off, but someone has since told me that if you thank the person as you hand over the money, they will assume the excess is a tip and not give any change.
So, either beware of thanking people too soon, or of not getting your change (depending on what you choose to believe!).
