Kiosk / self serve / honor system

Hi all!

I was wondering if anyone has any experience with Kiosk set ups. I’ve had the opportunity to make juice on location and use fridge space in a restaurant/cafe. I was hoping to use a square terminal to have a self serve option so that I don’t have to be present. We live in the country and many farm stores do this with their products and I thought it would be a cool way to offer juice without having to be physically present.

Has anyone used the new square terminal ?
Has anyone managed a juice kiosk ?
Has anyone rented fridge space in a different location and what we’re the operating written terms like?

Any information is much appreciated!

Thank you
