Telling customers to Shut the F*ck Up probably isn’t a very good technique for advertising, but apparently that’s one that works for European budget airline Ryanair. Customers get to fly cheap, they don’t get to complain. As the tagline says, With Prices This Cheap, Shut The F*ck Up. Surprisingly enough, the campaign seems to be gaining traction and bagging awards. Apparently, customers are fine with being told to STFU as long as they pay the comparatively low fair.
