I am reminded of travelling to the US as a very young boy with my father, on a BOAC VC10.

steward to Dad ;" can I hang your jacket Sir?" (in economy!)

Dad to steward, joking; " thank you, its about to lose a button"

steward to Dad, not joking; "Ill have one of the girls look at it Sir"

Jacket returned at end of flight with button resewn!
