Approaching T5 fast track at the weekend, there was a bunch of around half a dozen or so 20-25something year old's heading for it just ahead of me.

Of course, when scanning their boarding pass, it says no.

Leader of the pack shouts out "BUT I HAVE AN AMEX".

Clearly hoping to get the whole gang through on a single AmEx, I suspect they felt a bit of a wally when being turned back and sent to the regular line, which was stretching back WAY further than I've seen it any time recently.
