How to get water without getting tube of water???

[avylol08]

I got the seed, dirt and water pill, but I never got the tube of water. Is there any way at all to get some water from a sink? Is there a container I can find for it?

If you missed the tube of water then you won't be able to plant the seed this run, but don't worry too much as it isn't necessary to progress the story.

Happened to me too, it's a big immersion breaker if Maize dies for good because Niko can't pick up a jar, or a watering can, or a coffee cup, or borrow a jug from the cafe. The first zone transition teaches you that you don't carry objects between the sections of this adventure, but then you're supposed to for the second, and it's something as generic as 'container of water' that's somehow not available in a populated city?

We had a bottle from the beginning, why did we throw that away?

... and having now run oneshot.exe for the last time, I should note that the first playthrough will be many players' only opportunity to complete this side quest. OneShot is not a game that's suited to reruns for achievement/completionist reasons.
