Water Price

One thing I noticed when away on a holiday in Greece, was that all water was priced the exact same and very cheap at that. When eating out in any restaurant, it would even be free (bottled water would be free). It wouldn’t cost more than 50 cent, no matter the brand or the shop in which it was bought. In my opinion, I believe that this should be introduced everywhere. Water is something that should be priced the same, no matter where you buy it. It shouldn’t cost 1 euro in one place and 4 euro somewhere else. Water is something that will always be bought, because it’s something we need as humans to survive, so selling it very expensive in my opinion, is just greed. Plus, I just don’t think it makes sense for the exact same bottle of water to be sold for 1 euro somewhere and 3 or 4 euro somewhere else. How could we change this, do you think?
