I have plenty of time to get to dentist. It takes 20min to get there, I have 40. Check bike tyres, front is very soft. Pump it up. Ride to dentist, get there 20min early. Front tyre is very soft again . . .
Oh bu&&er
It's my town bike, so of course I don't have pump, tube or patches with me.
Post dental poking and prodding, I walk to train station to go to work - it is 2miles.
Could have fixed that at home in 10min. I was waiting 20min for the dentist.
