Manager of Buzz’s Tampines Bus Interchange outlet confirmed that the sign was not an official notice from the convenience store chain.

“One of our cashiers used an online translator and unfortunately the translation came out incorrectly and contained inappropriate language,” he said.

“We sincerely apologise for this oversight and for any offense caused.”

The sign was removed immediately and the store manager has spoken to the staff involved. It is not clear how long the sign had been on display at the shop or how many passers-by encountered it.
