I think they were negative points, as seen on QI
This puncture was repaired in a nice warm office, over lunch, and was def 100% pukka when refitted. I have been fixing punctures successfully for 20 years ... the quick patches didn't want to take either, but that was becuase the bus shelter didn't afford that much protection, and I couldn't find any completely dry clothing to wipe the tube.
I didn't have a spare with me this time, becuase I was on another bike to my normal commuter - someone having helpfully driven into it a while ago. I've tried, not altogether successfully, to try and get a 2.2 tube in a 1" tyre before now, so being rescued was a better option than to play that game.
I love this forum. I know exactly what replies I'll get before I post. Occassionally though, you get a nugget of wisdom I take it nobody knows on this Q though ...
