What is this machine in Wall Market?

While in what appears to be public toilets in Wall Market, I noticed this vending machine:

strange vending machine in wall market

When approaching it, there's no action available, and can't see any writing on it.

What is this machine? Does it have any purpose?


Solution 1:

After looking at the vending machine more, I remember the purpose of this vending machine.

While there are no actions available to interact with it, you can interact with it during the The Party That Never Stops side quest.

The items you will obtain will vary based on how many enemies you have scanned with the Assess Materia. Inevitably you will receive a specific item for the quest, "The Sauce", which continues the side quest and thus making the vending machine no longer interactable.
