Whilst any individual case may still be sub judice, the Blunt Ones should perhaps note that individuals may soon start refusing to carry large amounts of company cash with them and will pay bills only with a company credit card. Then crew allowances will need to be paid in advance either in cash or to an individual's bank account, leaving only unexpected itinerary changes to be dealt with upon return. Disputed bills will have to be referred directly to OC Accounts Flt. Captains will not sign Flight Sub Imprest paperwork, that again will be referred to OC Accounts Flight.
The archaic system of the co-pilots carrying large bags of swag around the world will have to stop and a much more realistic cashless system devised instead. It's time we moved on from the Dickensian system we have at present! Personally I prefer to use a debit card rather than cash; hence I've got various grubby little rolls of odd currencies stuffed into a beer tankard which I probably won't ever need; it would have been far better were they credited to my bank account in the first place and I'd only picked up nominal amounts of cash!
