Reimbursable Out-Of-Pocket Costs
  
You work for a large company. They send you traveling all over Creation, selling their wigs. When you're on the road and it's windy, you often need to buy extra glue at $4.88 a bottle. Then, sometimes, you need to Uber to a comb store: $12.34 the last trip. Then you get hungry, and they cover your meals up to 7 bucks (it buys a lot in Brazil).
These are all out-of-pocket (yours) expenses, for which the company reimburses you. You'll copiously track everything, put it all on one credit or debit card, and then submit that to the kindly old robot who handles reimbursements when you get back to the wig-growing ranch with all the long-haired alpaca running around.
Watch where you step.
