IT'S one of the oldest tricks in the book - and it's still working.
A customer buys an item and then confuses the cashier about the size of the note handed over and how much change they should pay.
The cunning trick comes in various mutations but can be known as the "change scam", "change raising."
Most managers teach their staff to keep any large notes to the side while they are giving change so there can be no dispute, but fresh employees inexperienced with handling money remain vulnerable.
Multiple areas across south-east Queensland are believed to have been hit recently by a quick change artist with such a scam.
A Noosa Heads business has been targeted twice.
The Sunshine Coast Neighbourhood Watch website said most of the recent scams in south-east Queensland had involved the purchase of a small item involving a $100 note.
The customer, upon receiving change, then offered a smaller amount, requesting the return of the $100 note.
But more exchanges occur while the customer pocketed and offered different notes, leaving the check-out operator confused about how much money they had changed.
According to Neighbourhood Watch, during the most recent hit at Noosa Heads last Sunday, two men entered the store and approached the counter with a small purchase.
One of the men offered a $100 note to pay for the item but distracted the check-out operator with the change and notes.
Police have released a description of a man who they believe may be able to assist in their investigation.
He is Caucasian, about 165cm tall, in his mid-20s, of solid build, with brown hair, blue eyes and a tattoo on his right inner arm.
He was wearing a white Everlast T-shirt with black writing when captured on CCTV.
Anyone with information should phone Crime Stoppers on 1800 333 000 or Policelink on 131 444.
