This is what customers do quite often:

And it doesnt always have to pertain to milk, can pertain to almost any item.



Customer buys too many gallons of milk

Notices the one in the refrigerator is expired

Takes the milk with her to the store, leaves it in car.

Goes in store to buy a fresh milk.

Goes back to car, puts milk in the car.

Gets expired milk out of car brings back to store

Produces receipts, accuses store of selling expired milk!!!

Gets money back!


And yes it happens quite often.
