A small French café has taken the old adage that manners don't cost you anything to its logical extreme - by charging extra to rude customers.
At La Petite Syrah in Nice, if you ask for "un café" it will set you back €7 (£5.80). If you also include the magic words "s'il vous plaît" you'll get the same drink for €4.25, however - and it's just €1.40 if you begin the order with a friendly "bonjour".
Speaking to the French edition of The Local, café manager Fabrice Pepino said his staff had grown increasingly fed up with the bad manners of people in a rush on their office lunch breaks.
"It started as a joke because at lunchtime people would come in very stressed and were sometimes rude to us when they ordered a coffee.
"It's our way of saying 'keep calm and carry on,'" he said.
