My old territory was East Texas, Arkansas, and Louisiana. Some places, there were only tourist courts. Most were small and spartan, but clean and operated by very nice people. One of our agents had a standard monthly travel plan, and the guy operating one tourist court, gave him a key to one unit, a pack of reciepts, and told him to just drop the money in the slot by the door each time.
Worked great until some expense account auditor in home office realized that the receipts all had sequential serial numbers. Took a while to explain that one.
