I think it was at RAF Brawdy (or it might have been the re-opened RAF Chivenor) where the admin mates, knowing how busy we were during the day, used to send a chap round to the flying squadrons to sort out travel claims. Which were settled in around 24 hours......in cash, not just BACS.
Bluntness is a mindset, not a branch!
Sometimes it's not the admin folks fault, but some faceless bureaucrat. There was a chaotic period once when mileage rates were amended retrospectively; the acker-bashers had to go back several months, check every claim and issue additional payments. It was evening and weekend working until they caught up....
Brawdy, Chivenor - them were 't days. Sorry, but they really were!
