Some items are functional. I made a mod for a Christmas kiosk with hot drinks, Christmas Market Beverages, for the game FS 19.
You can sell: sugar beets, sugar cane, water, (and honey if there is one on the map).
Features of Christmas Market in the farming game:
- Christmas kiosk as a decorative object: 200 rubles;
- Christmas kiosk for passive income: 3000 rubles;
- Christmas kiosk as a point of sale: 1000 rubles;
- Passive income: 60/40/20 rubles per hour;
- Permanent table: 50 rubles.
