The coffee from the machine in the office is even worse.

The last office I worked in not only had terrible coffee, but the machine had a touch screen and required network connectivity and regularly crashed, prohibiting all dispensation of coffee. It also reportedly came with a 5 figure monthly operating cost.

The coffee in the lobby was only slightly better, but at least the baristas didn’t crash during their OTA updates.

A 10 minute walk away and you’d find the best coffee for at least a couple miles around.

Visit us. You'll be surprised. :D

Now find the correlation to the quality of coffee to how recent the latest funding round was.

We buy our own coffee and equipment. The quality is constant. The only variable is our mood, which might affect the measurement from jug to jug, resulting in slight taste variations.

OP found no correlation between railway proximity and quality

OP failed to reject the null hypothesis of no correlation at the given power level.

Sometimes in another office building's lobby.
