I had an appointment at 5pm with a hypnotist - and so off I set. The courtesy car got about 6 miles then started flashing a warning light at me and over heating. I put more water in the radiator - and carried on. It got me to where I was going (just) - but I didn't trust it to get me home again so I called Posselq and he came and picked me up.
The courtesy car is now abandoned in a pub car park - and once again I am without wheels. I can feel some 'shouty' phone calls coming on :)
