In a way it's a relief, no more getting to the end of a shift wondering if Darwin would lend me a shotgun so I can clean up the gene pool for him.
Add to that the ambulance chasing parasite/scam artist preying on the vulnerable/vulture profiteering from the banking crisis by the end of a day I'd be feeling a tiny bit marked off.
On balance I don't think I have the temperament for telesales.
