What should we stock in our new London shop?

You're the only basic tool outside if you can't be bothered to pack spare or at least a glue less patch - it will fit in your pocket with a couple of levers and a mini-pump, Xander.

It was a stupid mistake but i took my toolkit out of my bag one night because i had to do some work on another bike i did have a spare inner tube with me tho.
got a puncture at 4am and was stuck with a new inner tube but no spanner to take the wheel off! fail
