I am evil Ratbert on P-class flights. I ALWAYS pay by credit-card, typically flashing the EBG DC card just to make things slower, and also ensuring that I don't get any grumpy comments in return. Hopefully my disobedience will make their life so miserable that they see the need either more FAs or free basic service.

That said, the "matpakke" you get onboard is actually quite tasty...
