Sadly, I got another one, from just this morning.
Scenario: We're sitting near the gate at an outstation, waiting for our flow window into our hub to open up.
Anyhow, we're facing a 3-hour delay. A passenger comes up to us and quite aggressively asks, "How long is this delay going to be? This is ridiculous!! I have an international connection!" We're used to this sort of stuff, so we patiently explain why flow control exists, how we're frequently in touch with the company and ATC to see if there's a chance for an earlier window, and so forth. We're patient and apologetic, just like you'd expect.
This doesn't satisfy the passenger. She starts the usual rant about inconvenience, delays, how this late flight will ruin her life, etc. Of course, we continue to apologize, etc....
Wait for it...
wait for it...
Finally she storms off in a huff, but not before declaring "Next time I'm going to buy a ticket instead of non-revving!!"
I wish I was making this up. I really, really do.
PS The flight after ours was cancelled, so we took all of the revenue pax from that flight that we could fit. No non-revs made it on board.
