Soda
A drink, not a well
Short answer
Soda helps a meter and a mood. It does not replace a pump. Cans rattle if you sprint them.
Also: pepsi · cola · fizzy
How it works
Soft drinks are loot, not infrastructure. A well is still the plan. Empty cans can become something else — inspect.
What to do
Drink it. Don't build a personality on cola.
Don't
Don't skip the well because you found a Pepsi.
