I love.. no i adore that concept and let's bring it to all our kinds of entertainment and enjoyment!
Hated the movie? Awful food or drinks at the restaurant? Had a bad time on holiday? Didn't get the correct mileage on your car? Called by stupid call centers on your mobile phone while your cell phone was in roaming mode? Commercials you don't like? Too much popups in your browser? Windows 7 grinded to a halt? Your videogame sucks?
Get your money back and/or money for compensation of the time you spent!
