On a 777-200 going to YUL many many months ago...:
Me: Would you like a tea or coffee?
Capt.: Yes, tea please... Milk and 2 sugars. Can I have it in a First Class mug...?
Me: No... (no chance to continue with the sentence before...)
Capt.: WHY NOT? I want it in a bigger mug....!
Me: It's a 3 class 777, so there is no First Class...
Capt.: Oh, um, OK, a deli cup then? :-/
FO: *peeing himself laughing*
