At Check in....
Sitting on a Ryanair check-in desk some years ago...my partner working the flight with me had some real minor soap actor "celebrity" at her desk - as usual he had too much baggage and didn't want to pay and was becoming agressive and rude...he uttered the immortal words...
"Do you know who I am"
Quick as a flash my colleague stood up on the baggage conveyor and shouted to the packed terminal...
"EXcuse me everyone - We have a man here who doesn't know ewho he is- Can anyone help him out..."
obvious laughter from everyone around him who had overheard - he shuffled off to pay red faced and a little more humble!
