Spanish café begins charging more for coffee if customers are rude | The Independent

"A café in Spain has begun charging its customers more for their coffees and pastries if they are rude when ordering.  Restaurant Blau Grifeu in Llanca charges rude customers €5 for their morning pick-me-up while those who behave more graciously pay just €3. Saying 'please' and wishing the barista a good morning will get you a coffee for as little as €1.30. "
