Pot-filler spiggit

We toured some very large homes in Punta Mita while in Bucerias and in one of the kitchens, I noticed this funny tap. It is a pot filler. You put your pot on the stove and then just fill from this faucet rather than lugging your full pot across the kitchen. My question: How does one empty the pot after use????????????? You would still have to cart a large pot across the floor to the sink to empty it! Unless of course, you have staff!

It is sort of in the middle of the photo.
