Got bumped from cattle class to royal class (sic) on a flight when I was a kid. Got to taste real caviar. Black, salty, fishy and rather fatty. Bit gross really.

Also got asked for a drink (alcoholic, I guess I was old enough). Cattle class you got the drink. Royal class you got a saucer with a coaster with a doily with a smaller coaster on that finally with the drink parked atop, and a tiny fork next to it to pull out the olive in the drink, which it didn't actually have because it was baileys. Hmm.
