Held up

I walked into a bank and asked for change for a fifty.
The teller asked, “Are you a customer here?”
“No,” I said.
“OK well I’ll do it just this one time. Normally I wouldn’t because this bill could be counterfeit and I want to protect our customers from fraud.”
“Ha! Your company committed major fraud against your customers.”
“It wasn’t
that much fraud.”
A little bit of fraud is OK.
