There are still people who believe Jesus meddled with the OH groups on the water molecule and that would count for a miracle. For others Jesus was the biggest looser in history. Having discovered how to turn water into wine he failed to materialise on this wonderfull business opportunity. He would have been rich beyond his dreams if he would have sold the product for a premium price. Perhaps that was not his dream but the owner of a vegan restaurant in London does not want to let an opportunity go by to turn water into DOSH. Where the famous British Delboy and even the inventors of Father Christmas i.e. Coca Cola failed to con the public he openly admits using tap water but "improving it" by running it through a £12.000 ionising machine to increase the value of the water from 0.1 penny a litre tab water to £1 per litre, a wopping 1000 fold increase in value. Now most people would agree that this must be "holy water" to deserve such a profit margin. It is said to come with a pH of 10 being very alkaline and therfore much more healthy than tea coffee or alcohol and protect you from all sort of things (apart from being ripped off). Apparently the cost in the restaurant just reflects a mere service charge and you get your refills for free.
Now for £12000 ionising machines are too expensive so surely the next gadget on the market will be a battery (or solar cell) operated ultravioled LED safely encased to protect you from the dangerous ionising radiation but giving your tap water that holy glow, destroying harmfull bacteria but enhancing the health benefits of your water. You still have to pay a inflated price for it as the higher the cost the more potent the treatment but for a couple of hundred pounds you can sell it to the wider public. If you than perform a little tap dance around the tap you can declare it new age water, at least twice as valuable as simple ionised alkaline water which in the inner circles is refered to as "snake oil" on tap.
Shame on those primitive cultures who belive that as a basic gesture of culture you should -if you have it- offer any person a free drink of clean water as a basic sign rule of hospitality. After all it is the essence of life on earth and you could have neither wine nor beer without it. However hospitality is for hospitals, not restaurants. That is why so many people go there after a "good night out". It looks like adding our spirit to the water is what makes the water so expensive and we are used to pay a hefty price for it in more than one way. However the devil lies if not in the spirit in the detail, something being expensive should not be mistake for being valuable.
