By the way, you youngsters won't remember this, but back in the old days (like....the 80s) we used to get water from the most ridiculous place ever....the sink. And, WAY back in the 70s, we cave children would drink from (gasp) the garden hose.
I know what you're thinking. "No way! The sink is just for rinsing the man's pesticides from your veggies and washing free range egg residue from your responsibly sourced living wage spatula!" Turns out, you can actually DRINK the stuff. Who knew?????
My (obviously sarcastic) point is that if you can't find bottled water, go to Lowe's or Home Depot and buy yourself some 5 gallon buckets. Wash them out. Fill them with water ftom the sink. Also, fill your tub with water. Use the containers you would otherwise keep your avacado toast juice in for water. (If avacado toast juice isn't a thing yet, it will be.) Old fashioned water won't taste as amazeballs as "real water" from a bottle, but it'll keep you from dying of stupidity.
(Relax, we're just having fun here.)
I would have died from dehydration a lomg time ago if it wasn't for garden hose water. Oh, and the brown water running under the highway where I used to fill up my bicycle water bottle when I used to commute on bicycle. It looked nasty, but man it tasted good! Almost as good as avacado biscuit juice.
