However, it is the change in Toblerone's shape, more than its size, that has prompted much of the consumer ire.
Toblerone fans, we have some information on the size of our United Kingdom chocolate bars.
But Mondelez International, which makes the Swiss chocolate, have now revealed their reasons behind the controversial move. The taste of half of them has changed since you divested from Kraft and quite frankly I can purchase better Lidl. It chose not to increase the price, but to lower the weight of several chocolate bars.
The company announced upcoming changes to the product last month, writing "We are experiencing higher costs for numerous ingredients", in a post on the Toblerone Facebook page.
The 170-gram and 400-gram milk chocolate bars have been downsized in only the U.K.to reduce costs, according to parent company Mondolez International.
Britain originally received two variants of Toblerone, a 400g bar and a 170g bar, which have now been reduced to 360g and 150g respectively.
Toblerone and Mondelez maintain that despite impassioned fans disappointment in the new shape, there has been no change in taste.
She said: "This picture of our bar this evening seems to be different to yours?"
'Strange' weekend at the box office
The World War II drama sees the return of director Mel Gibson and has high hopes of being a contender for awards ceremony. It took in an estimated 118.7 million dollars this weekend in 53 markets, growing 38 percent than the previous weekend.
Garry Cornell wrote on the Toblerone Facebook page: "Terrible decision".
A third, Allison Reilly, asked Toblerone bosses: "What's going on?"
'In fact I felt cheated on a tad in the way that they are now spaced out so much loosing out on toblerone goodness, I'm upset toblerone I'm sorry but I really am'.
Many feel deceived by the switch, since packaging and pricing remains the same.
This led some furious customers to vow to give up Toblerone altogether. Many believe the decision to leave the European Union, which has already had various affects on the local food and restaurant industries, is now wreaking havoc on a beloved chocolatey treat.
Cathy White added: "It looks terrible".
For many, the Toblerone is linked to travel - a gift purchased at the airport before boarding a plane home - though it is increasingly available in supermarkets and shops.
