Happened yesterday, lady pax actually
complained that out duty free prices on cigarettes onboard were
cheaper than in the duty free shop at the airport! She argued that it shouldn't be the case, to which I replied: "I am really sorry, Madam, I could try to charge you more but Im afraid the computer won't let me!" (I don't think she got the message, bless her).
But then again, what do you expect when pax sometimes get upset if we land 20 minutes early! Can't win, can you?
Also, today, during disembarkation a man two rows from the back galley where I was stood idly presses the call button. Knowing he didn't want anything, really, I asked him politely; "Sir, why did you press the call button?", to which he replied distractedly: "Oh, well, I just wanted to see what happens". ("So, basically, you are just bored").
