In morocco, we have restaurants with sinks near the front, exactly like a sink you might find in a bathroom in a house, and next to that sink is a copper cup attached by a chain to the wall. And people are free to come in and drink from that. I always wondered why the humble fountain wasn't more popular
Maybe the water waste in fountains feels worse in drought-prone regions? Even if the amount is comparably tiny, watching a precious resource just vanish down the drain might be hard to stomach?
I'm basing this on nothing, by the way, but it feels like a fun hypothesis.
