There’s a Coffee Shop in France where not saying “hello” and “please” makes your coffee more expensive.
Walk up to the barista and say, “One coffee.” That’ll be 7 euros. Or say, “One coffee, please.” That’ll be € 4.25. But if you say, “Hello. One coffee, please” then all you have to pay is € 1.40.
At the Petite Syrah in Nice, France, it pays to display proper gentility. The manager, Fabrice Pepino, started it as a joke after encountering too many customers who dropped their manners when they were in a hurry.
So far, he hasn’t had to enforce it. Mr. Pepino says that when customers notice the sign, they slow down and watch what they say.
