There is a cafe chain in Russia that charges by the minute but most drinks are free. They tried to expand to the U.K. in the mid-2010s, but their test cafes failed, and they pulled out after a few years.

It's quite reasonably priced actually, and a bit more co-working focused than your average coffee shop.
