A picture of a McDonald's competition receipt with the prize money in Chinese yuan instead of Australian dollars has confused customers.
An image of a suburban Adelaide docket for the burger chain's Summer Cash Giveaway shows the prize money given next to the symbol for the Chinese yuan.
'Enter the unique code above for your chance to win 1 of 10 ¥ 10,000 Cash Prizes,' it reads.
This is the receipt from a suburban Adelaide McDonald's uploaded to internet discussion site Reddit on Sunday. The Chinese yuan symbol can be written with one cross-stroke or two
The receipt is from McDonald's Summer Cash Giveaway promotion
Daily Mail Australia understands the typo was only in replacing the '$' sign with the '¥' symbol.
That is because the Summer Cash Giveaway official website states the top prize for the promotion, which ends on December 31, is $10,000.
If ¥10,000 Chinese yuan were paid, then converted to Australian dollars, it would only amount to $2,014.
By contrast, $10,000 in Chinese yuan would be ¥49,636.
The image set the internet ablaze with delight at the corporate snafu.
'China has hacked maccas in Adelaide,' one wrote.
'Can you imagine the outrage that this photo is creating somewhere on Facebook?' another wrote.
Daily Mail Australia has emailed McDonald's for a response to clear up the mystery of the yuan.
The Chinese yuan symbol can be written with either a double or a single bar beneath the fork.
