During a fuel-stop in Anchorage (in the middle of a snow storm) the girls in the back asked for a bag of ice. The handler arrived with a small bag of ice and an invoice for $ 75. Both ejected from the aircraft.
Then there was the crooked Irishman at the Atlantic FBO at LAX (who used to set up colonic irrigations for the hosties) who produced a catering invoice for $ 48,000 for 9 pax (2 services). What a circus!
