In 23 years of employment I've only done one kind of job. Retail IT. That's computers, in and for Retail (and Wholesale) companies.
And there's a rule. Whenever you start a new job in Retail IT, you get to go to the stores to work for a couple of days to see what it's like.
Which is why I'm going to spend the next couple of days selling curtains, rugs and cushions.
I wouldn't want it any other way. But it's not really "incarnational". Because in 2 days I'll know what it's all about and will go back to my life of living on the shop floor. But the 5 days I spent in the China Department at John Lewis were some of the most fun I've ever worked.
But I still wouldn't want to do it for a living.
