Manners are important. Holding doors open for people, saying your pleases and thank yous, refraining from eating your friend's French fries. These are the hallmarks of a polite society. However, as anyone who has stood in a line can attest to, politeness is not always a given. This French bistro, though, gives one heck of an incentive to remain civilized.

La Petite Syrah in Nice, France has instituted a new policy. If you aren't polite, your coffee and treats cost twice as much. The menu features a tiered format that offers different prices depending on how nice you are to the staff. Saying "please" and "thank you" and being generally amiable nets you the biggest reward. Being a major turd, however, will empty your wallet.

The cafe's owner says that the new policy has made a noticeable difference in customer interactions, with people smiling more and being altogether nicer. Don't expect this idea to travel across the pond, though. Being impolite is a God given American right.
