We ended up paying £27 each for meal ((3 x £10) - (3 x £1 in change)) + £2 tip = £29 in total.
Never did figure out where the missing £1 went from the original £30.

Ah. Bistro Math.
If you had not added the bit about it being a riddle, it might have taken some people longer to figure out... then again, people might have been a bit more stern with you for your error.
(About 45 seconds, in my case. Sorry, z-chan. I don't enjoy doing this sort of math, especially first thing in the morning, but since it was a riddle I thought I'd look it over to see where the "trick" was. Oddly enough, to me it didn't look like a riddle at all, just bad math. I'm far to literally-minded about these things.
