U.S. Marine veteran Jeffrey Duck got locked inside a VA clinic in Orange City, Florida, on Monday.
Duck entered the clinic as a walk-in patient at 1 p.m.
He waited in a consultation room for more than three hours, but then realized the clinic was locked and everyone had gone home.
"I was apparently left there and forgotten," Duck told ClickOrlando.com (video below).
Duck used his cellphone to film himself walking around the lobby because he was concerned that he might be accused of stealing something, noted the Associated Press.
While he filmed himself, Duck accidentally set off a burglar alarm, so he called 911.
"I apparently got left in a VA facility, a medical facility, and the alarm has been going off," Duck told the 911 dispatcher.
The Veterans Administration issued a statement on Tuesday: "We want to apologize to Mr. Duck for his experience yesterday at the Orange City VA Community Based Outpatient Clinic. We are looking at our closing procedures and will make changes to ensure that this does not happen again."
"I'm kind of disappointed, really disappointed," added Duck. "There's a lot going on with the VA right now; they're all over the news. Everybody knows what's going on with them. There's a lot of people with bigger problems than me."
Duck was treated this week at a VA facility in Orlando, Florida.
