► Firstly I would check with the Flight Attendant to make sure I heard and understood everything correctly. It would be terrible to falsely accuse someone. Maybe I had miss-heard.

► If the Cabin Crew seems to be genuinely at fault I would report it to a senior Flight Attendant. The reputation of the company and the enjoyment of the passengers is of course a very important concern.

► If I was the direct superior of the Flight Attendant, I would ask them the circumstances of the incident and take appropriate action. The crew would be given a verbal warning but the incident would be recorded in the crew briefing note.

► I would also approach the concerned passenger to find out if he was at all affected by his encounter with the crew and try to fix the situation.
