Subscribe for chilled + filtered water
The IoT has gone so far as to make smart water fountains a reality. Reefill stations are basically fountains where you can refill plastic water bottles. The point of this system is to reduce plastic wastage. An advantage that Reefill offers over traditional water fountains is that it even has chilled water to quench your thirst.
The catch: you gotta pay a monthly subscription fee. Non-chilled water is free, so non-Reefill users can always get a drink of water. The paid subscription program is a weird concept, but if you think about it, you could end up saving quite a lot on drinking water.
