Snobby passenger and Wifey at check in.
Two desks for the flight, both closed, with a single orderly queue.
Said couple rock up, and in a stuffy voice she's says, " I'm not standing in that line."
So he dutifully leads the way to start a new queue. My response to which was that's quite an assumption.
Check in girl comes out and sets up the desks and the first queue bunched up a bit.
When the flight finally popped up on the screen, I walked up to the desk and asked which queue was the one for Business. Turns out, it's the one Mr and Mrs Stuffy started. So I plonked myself in front of them, which raised an eyebrow from the check in lady.
After a prod from The Wife, Mr Stuffy taps me on the shoulder and asks if I am alright.
"Yes thanks" I reply.
"Oh, it's just that you've walked straight to the front of the queue."
"Well, you had already presumed to do that yourself when you actively didn't join the existing one."
"Oh", he says, "Ah, yes".

Best he could come back with, to someone else was that there's no rush as we're all on the same flight

And for the record, I am not using my staff travel... A full business fare was actually cheaper than the concession one.
