Lost: the Bank Statement

Pete may have lost his bank statement.

"Did you call the bank?"

"It's too late; they're closed."

"Did you go up to the bank and look for it on the sidewalk?"

"I had a couple of cups of wine before I discovered I lost it."

Now, at Pete's table is Stu. Stu used to be a banker. It is Stu's considered opinion that no one can get into Pete's account with the bank statement. Of course, Stu knew every single one of his customers by name and he doesn't understand that the new teller on the hill wouldn't know Pete if he bit him unless he ran his DNA.
