TESCO has launched an urgent investigation after its staff apparently confused milk chocolate with white chocolate.
Sweet-toothed shopper Shannen Doherty (@shan_lou_doh) went to purchase a bar of chocolatey goodness from the shelf labelled 'milk chocolate' at the Tesco Express in Lower Addiscombe Road.
But when she returned home, she found the bar was more Milkybar than Dairy Milk.
She tweeted Tesco's official Twitter account: "Err @Tesco I think your staff need chocolate training! #definitelynotmilkchocolate #milkchocolatedoesnotmeanitsthecolourofmilk free cookies?"
Tesco was quick to reply to avoid the blunder becoming a serious PR gaffe and said they would look into the situation.
Ceri, who was manning the Tesco Twitter account, told Shannen later: "I have fed this back to the store so that it can be addressed. I hope this helps."
It has not been clarified whether Shannen will receive any chomp-ensation for the mishap.
