One man's lucky day soured Sunday at Market Basket when police said he discovered the $100 bill he used was possibly counterfeit.
At 6:31 p.m. Sunday, police said they responded to Market Basket on Highland Avenue for a call about a counterfeit bill.
The man "found what he thought was a $100 bill on the streets of Lynn...Thinking it was his lucky day he went to DeMoulas and did some grocery shopping," police said.
When he went to pay for his groceries, he presented the clerk with the bill, which was checked and believed to be counterfeit.
The store manager told police he knows the man is a regular customer "and he notified police to file a report and retrieve the bill."
