They are probably welcome to it given that when Coca Cola launched it in the UK it was found first to come from water in Peckham (a well UK sitcom previously covered an attempt by a fraudster attempting to sell Peckham Spings water at a premium).

In fact the Coca Cola launch was a textbook example of how not to launch a product.

It started with the tag line

I assume because US executives of Cola did not understand than Spunk is a a British euphemism for something entirely different from what they intended (I hope so anyway). Know your market.

Then the Food Standards Agency found quantities of Bromate far higher in the water than legally allowed. [Don't poison your consumer] This and front page headlines that this was basically processed tap water killed the brand in both the UK and the wider EU.
