In the checkin queue at Dulles two years ago with a couple of hundred in the WT lines, half a dozen in CW and 3 of us in the F line. The WT desks opened first and started calling pax forward and this caused a 30 odd year old American who appeared to be travelling with his parents in the CW line to go bananas, bawling at the staff "BUSINESS CLASS HERE!!".
As our desks were just setting up the lady nodded to us to come forward only to be overtaken by Mr "BUSINESS CLASS HERE". He and his rather embarrassed looking parents were sent back and told "this is First Class, Club World will open shortly."
If I'd behaved like that in front of my old man he's have clouted me round the ear!
