Anyway, one of my colleagues was this evening in a right lather, unable to get a garage to come out to fix his puncture - apparently getting the wheel off a motorbike is no mean task. In the end, I think, he had to abandon his wheels and take the train home.
Any useful tips I can pass on (when he's more or less conversational again tomorrow)? How often does this happen?
