What this means of course is that I'll be forced to drop by a Tesco on the way home on Monday and pick up some things. Or if there's duty free shopping past security I guess I can get stuff there, but I've a feeling it won't be cheap. Or I could just check in a bag. Though that would involve bringing two bags, as I wouldn't want to stow my laptop below.
I'll figure something out, I have a couple of days anyway.
