Loc, I'm with you on the optometrist wiggling about.
I really had to bite my lip to stop myself laughing in his face. Don't think it would've looked too professional!
Got back to Gatwick and had a couple of hours to kill before meeting a friend in Clapham and realised they'd got my name wrong on the medical certificate. They'd managed to put my middle name as my first name so had to go back and get that changed!
