Andrew Merritt asked the 88-year-old if he could spare a couple of pounds and the pensioner, who was on a mobility scooter, took out his wallet and gave him £3.10.
CCTV footage showed Merritt then hug the man before grabbing the wallet and walking away.
As the elderly man pleaded for it back, Merritt grinned as he counted the large wad of £20 banknotes from inside the wallet. He kept the cash and dumped the wallet.
