It “clearly” says, “USE APP TO ACCESS”, so no, you can’t just push the button. It has to verify your subscription first.
It only requires the app for chilled and filtered. The regular tap water is still available.
@ch00f@lemmy.world said, “Even if it was free…” which implies he’s talking specifically about the paid button on the right and not the free button on the left.
The implication being even if the chilled and filtered water was also free, having to open an app for the button to work would be bullshit.
