My "congrats" when a first class SH1T was promoted in Met. :
"I suppose I should congratulate you on your extreme good fortune!"
"YES!" he preened.
"Gotcha!, you thick sod!"
Turning down promo is/was the most difficult decision. I was guaranteed next post as SMetO Wildenrath, a plum job.
Then the phone rang and I was offered PMetO 1 Group Bawtry.
Very very difficult with 4 children in the education years, happy at Queen's School Rheindahlen, and all doing well. Vanity won.
Still not sure ...........
