A Belfast hotel is charging £26 for a fancy bottle of water. How much would you pay?

Now - next up Watergate. Would you pay up to £26 pounds for a bottle of fancy water? The Merchant hotel has launched a new 'water menu' with H2O from around the world including Canada and Fiji. And has even appointed two new water butlers that can help guests choose the water that's right for their palate.

Is this an over indulgence? Or if people have the money why should they not spend it on what they want?
