Leaving your wallet somewhere can ruin your day.

A bank robber leaving his inside the bank he just robbed can ruin a whole bunch of days — like up to 20 years worth.

Especially if the wallet contains a couple of photo IDs.

But that’s what Albert Vincent Perkins, 39, of Kansas City did Thursday, according to a complaint filed by the U.S. Attorney’s office.

He was, reportedly, a nervous sort.

The FBI said a man carrying a wallet in his hand entered the First Federal Bank at 4227 Blue Ridge Blvd. about 9 a.m. Thursday. He placed the wallet on the counter and told the teller to be quiet and give him all the $100 bills.

The teller put $3,129 into a plastic bag the man gave her.

The robber, who acted “agitated and nervous,” then left the bank, leaving behind the billfold. The teller and a customer both identified the robber as being the man in a driver’s license photo and another photo ID found in the wallet.

About 10 hours later, Kansas City police stopped a vehicle matching the description of the one used in the bank robbery.

Perkins was inside the car, presumably without his driver’s license.
