In October 2013, a café in the South of France implemented a pricing policy based on patron’s politeness. Patrons who greeted the barista at La Petite Syrah and used ‘please’ were charged EUR 1.40 for a cup of coffee; those who failed to use any pleasantries were ‘penalized’ with a EUR 7 price. The prices (with greeting) were clearly displayed on a board inside the café.
Interesting idea, especially in an era of trolls and endless complaints.
