Touch'n'oops - that is a fabulous collection.
I did enjoy listening to a pax at ticket counter in MUC a couple of years ago ...
It was Clock Change Weekend and an American Tourist had not noticed this and arrived too late for the flight back to the USA. She was sent to the ticket desk to change for the next day.
After listening to the pax repeating: "But I HAVE to be on that flight!!!" The agent said quietly, "But the aircraft has already taken off." Pax didn't say anything after that.
