We can do that here in the Mid-South, too. Got a story you might like. The customer, service desk which allows some cash back for free was packed. So, I had to go to register with something to buy. I tried to minimize the cost overall for a $500 withdraw at a company with $100 max per transaction. I hit their self checkout. I did five orders on the machine each with a
single grape. Each order was
one cent plus $100 cash back. Total transaction cost was
five cents.
Self-checkout person was going "what the hell?" on that one. I also heard her talking to others about being hungry from break being delayed. I gave her the grapes after explaining what I was doing. She was happy, too. Probably did it herself at some point haha. Cashiers trip out to this day if I tell them about that whenever someone is buying a candy bar or something to get cash back. Occasionally, person in line leaves to get a grape. Just one. :)
