Bags of actuals
Once sent on a 3 week det and made to go on actuals for the whole period. I put a large box in the det ops room for all the crews to donate their receipts. At the end of 3 weeks I presented the chief clerk with 2 dustbin bags full of receipts and asked for my money! After returning to my office I had a call from OC Accts to ask if I would mind having rates instead!
I of course accepted her offer. Following year the subject of actuals was not even raised !
