i remember on the 767 with XLA on a flight back from RHO to LGW when my friend on the double cart with me stopped at a lady(and i use that term loosely):
f/a:"would you like a hot meal madam?"
pax:" yeh what you got?"
f/a: "theres a choice,chicken or beef"
pax: "show me the beef.....(hands meal to her)..that looks like
dog sh*t"
f/a: " well we do try to tailor our meals to suit our passengers
madam"
she then took off the brake and continued.Unfortunately the joke went way over the passengers head.
