Milk vending machine

A milk vending machine has appeared near us. You buy a bottle the first time, then you can get a refill.

The sign says:

Michelmersh Milk Vending
This project, funded by the Loddon and Test LEADER Programme, provided a grant to enable growth of direct sales to consumers with
the purchase of five milk vending machines and a milk delivery van.
It is part funded by the European Agricultural Fund for Rural Development, The European Agricultural Fund for Rural Development: Europe investing in rural areas.
