(I'll gladly drink whatever water I find, but I'm not a fan of the plastic taste of some bottled waters and definitely a hater of refrigerator-cold water)
From my holidays in the US I recall shops, even small ones, having lots of drinks. Like, shelves and shelves of any alcohol free drink (and some abv ones) one could imagine. Here I go to my neighborhood small supermarket and there's coke, lemonade, Fanta, tonic water, a few local products such as spuma and that's it
