Peter Marshall, 25, from the Isle of Man, made the discovery after dunking the treat from a box of M&S Extremely Chocolatey biscuits in a cup of hot milk.
As the chocolate melted away, he was bemused to discover the words “custard cream” within the trademark diamond shape of the family favourite.
He posted a picture of the biscuit on his Instagram account with the caption: “Marks and sparks are a bunch of cheapskates.”
Mr Marshall reportedly said: “I was dunking biscuits into hot milk and as the chocolate melted away I noticed that the base of one of the biscuits was actually a custard cream.
“I’ve always held M&S in quite high regard when it comes to food, and finding out that they were using a more common biscuit as a base was a bit of a shock.”
He said he would not be making a formal complaint and the episode had not put him off buying M&S biscuits in the future.
M&S assured customers that the biscuits were in fact a luxury offering, and the wording underneath the chocolate was simply down to the mould used to make the line.
A spokeswoman said: “Customers can rest assured the biscuits remain our own luxury recipe covered in milk chocolate. They are simply made using the same mould as a custard cream.”
Kids won’t tune out
Convincing children to turn off the TV or computer is more difficult than get them to do their homework, go to bed, or take a bath, a poll suggests.
Almost one in four mothers and fathers (23.1%) have trouble controlling the amount of time their son or daughter spends watching television or playing on computers, tablets, and phones, according to the Action for Children survey.
In comparison, just one in 10 parents (10.3%) found it difficult to get their youngsters to do their homework, while 17.5% struggled with getting them to bed, 10.5% had trouble getting their child out of bed and ready in the morning and 4.6% found it difficult to encourage their offspring to take a bath.
Customs at Heathrow
Tourists touching down at Heathrow are being introduced to British etiquette by a video starring comedian Stephen Fry.
Tips which feature in the short film include cheering when drinking glasses are accidentally smashed in a pub, navigating the awkward “after you” loop, and mastering the “agreement rule” when a stranger comments on the weather.
Visitors can access the guide on arrival at Heathrow via the airport’s wifi page and on its YouTube channel.
Fry collaborated with Fr Ted writer Graham Linehan to make the three-minute video.
“We’re a nation renowned for its sense of humour, unspoken rules, and little quirks,” Fry said.
“No matter where you go, you’re sure to talk about the weather, will need something waterproof to hand, and are likely to meet someone who feels the need to apologise profusely for everything they do.”
Has the draw been maid?
The Parent-Teacher Association of a Cyprus elementary school has come under fierce criticism for putting up domestic help as a prize in a children’s holiday lottery draw.
Cyprus PTA Confederation chief Maria Savva told state-run radio that a man who runs a placement agency offered to waive the fees and costs of finding a housemaid as one of the prizes in the traditional children’s draw at the Aradippou school. It is unclear if anyone claimed the prize.
