Sorry to here that... Far better to live a happy pauper than a miserable baron. Going to remember that line as it is rather excellent...
It's happened to me on a few occasions... and is rough even though I can't drive I have a full Motorcycle license but even that didn't cut it for one firm... even after pointing out to them politely that I could get to wherever they wanted me to be probably quicker than the guy in the car...
I currently work for a law firm if you want to drop me your CV and a covering letter, I can forward it to our HR guys... Head office is in Leeds but we have offices in London Sheffield Manchester Glasgow etc... also in most of the main cities in Europe like Vienna where I am currently causing trouble... drop me a PM and I will send my email addy over...
