Qu’est-ce que c’est?:

A cafe on the French Riviera has gained international notoriety after reminding customers to mind their manners.

What started as a local joke generated an internet buzz this week after a diner tweeted the sign outside the Petite Syrah in Nice on the Côte d’Azur.

In an attempt to turn the tables on customers who complain that serving staff are rude, the manager warned he would hit impolite customers where it hurts, in the pocket.

A sign outside the establishment states:

“Un café – €7 [£5.90]

“Un café s’il vous plaît – €4.25

“Bonjour, un café, s’il vous plaît – €1.40.”

The reader who sent this story to me asks, “What would be the American equivalent?”

Good question. A discount for not using one’s smartphone during the visit to the cafe, maybe? A discount for having children who exhibit good table manners? What do you think?
