A scammer described by police as ''loud and expressive'' has been ripping off South Island Subway outlets. Sergeant Simon Paget, of Cromwell, said a middle-aged well-dressed Asian man would purchase a low-cost item such as a drink, hand the cashier a $100 note and take his change.
Talking loudly and using expressive gestures, thought to be an effort to fluster the cashier, he would then say he had the correct amount in coins and ask for the $100 note back.
Meanwhile, he would secretly pocket $40 to $60 before handing the change back, making a quick exit before the cashier realised.
Sgt Paget said in one case, CCTV footage showed the man appear to drop the coins. It was thought he then slipped some of the change into his sock.
The man is known to have performed his ''practised routine'' at at least three outlets - Frankton and Cromwell on Sunday and Kaikoura on Monday.
