I got the impression if you don't permanently live within 90 minutes, then they are sceptical it's the right job, and i certainly baulked at that because I'm double that and don't fancy wasted days in a dive motel.
And I didn't know the MDs inside leg measurement, so it was a non starter. I did a practically identical operation in the past, and it's relaxing, but verging on boring, and rather unhealthy, so I decided to stay at my current gig.
