"Unfriendly" countries

Southern US here and it could very well kill you.

I can't say it's still like this, but when I was in Kansas City about 20 years ago, the hotel waiter poured me a glass of water and it tasted amazing and he said it was just tap water.

I'm from from between the south and midwest- and my city water utility always bragged about how its supposedly some of the best tapwater in the world.
