Part of the reason why Liquid Death is so popular is because it's the only way you can drink water at a shit ton of bars and venues now. All live nation venues only carry it.
And at many bars if you just ask for "water" and don't think about appending "tap" to it you get one, and get charged for it.

Maybe it's a hot seller at the grocery store and I'm unaware but aside from parties where it's purchased because it looks like a beer can and reduces the teetotal and DD stigma, it's mostly bars and venues fueling their success afaik.
