A store of the "at home" format, a complete list of mandatory goods, there are always fresh fruits and vegetables. Employees come in to buy groceries for lunch at the medical center, and also shop on the way home.
For a small store in an old building, it's not bad.
It's not the best choice, but the basic minimum is in place, and that's good.
(Update. Now there are often no basic goods, and the refrigerators do not work)
There are self-service cash desks
If you're lucky, the staff is friendly.
