Sorry, I beat you to it some time ago. See? That's also (in)significant.
I do wonder - AA allegedly saved $40,000 ~25 years ago when it eliminated one olive per passenger salad; NW claimed it saved $2M eliminating the pretzel bags.
For the trivia contest of all times, how much do you think AA saved by the extraordinary measure

of eliminating napkin / serviette buttonholes for First Class meals service? (And does anyone wonder what kind of bonus the erstwhile employee will be awarded? The head of Gailen David on a platter?

)
No button holes on the new napkins in first class.
