AIN'T NOTHING LIKE THE STEAL THING, BABY JUNE 23. A janitor at Corona del Mar High School obliged a vending machine serviceman by unlocking the caged vending area, enabling access to the cash-stuffed cola vaults. Clad in a brown uniform with matching hat and carrying a bag of money and a set of keys, the serviceman collected $1,000 in change from the machines and left. Shortly thereafter, another identically dressed serviceman arrived and asked the same janitor to unlock the vending area so he could collect the money. Oops. Turns out the first guy was an impostor. Police are searching for a man in brown with a jingle to his stride.
