My wife recently ran into a neighborhood acquaintance on a flight. My wife was in first class and the acquaintance was in coach.

When drinks were served, my wife flagged down the coach flight attendant and said, “please give the passenger in Seat __ whatever she wants and here’s my credit card.” (The credit card issuer reimburses up to $X in airline incidental expenses and we never use that benefit so it cost us nothing.)

When the flight landed, my wife ran into the acquaintance and the acquaintance said, “you didn’t have to show off by sending crumbs to the beggar in coach”.

So apparently sending a drink to a passenger in coach is entitled/pretentious/whatever?
