Marathon runners grab water bottles from random people all the time.

Or maybe somebody gets home from going to the gym and their water bottle is empty, but that’s okay because they see a glass of clear liquid sitting on the counter and they think ‘oh I must have accidentally left that there earlier’ so the grab it and drink it, but NOPE it’s apparently vodka for some random inexplicable reason.

Or maybe somebody is on a road trip through Arizona, but their car breaks down. That’s okay, there’s a gas station in 5 miles according to the sign near them. So they grab the jerry can but forget to grab their water bottle, and it’s 40+*c out. They finally get to the gas station, but the attendant just so happens to be in the bathroom. But OH, there is a glass of clear liquid on the counter next to an empty jug. ‘Must be free water for unlucky travellers like me’ the person thinks. So they grab it and start gulping it back but OH NO it’s VODKA. I guess the gas station attendant is an alcoholic who just likes to drink room temperature vodka from the pitcher.
