Eagle-eyed viewers have spotted a local petrol station in the latest Dairy Milk advert.

The Masked Singer viewers in the Kings Langley area spotted a familiar petrol station on January 14 when it popped up in an advert for the chocolate bar.

Gemma Flanigan, UK&I Associate's marketing director at Cadbury, said: “Our latest campaign Garage is indeed filmed at Hempstead Road Texaco.

“The film tells the story of a young woman working late at night in a petrol station when a customer accidently leaves a bar of Cadbury Dairy Milk on the counter after paying for it.

“Turning out to be the girl’s father who intentionally left the bar to brighten his daughter’s night, this small gesture shows how generosity brings us closer and that there’s a glass and a half in everyone.”
