That's simply not true.

VC funding distorts this, since at that point what you can afford is no longer based on productivity, but how good you are at convincing investors. As a customer of the cafe, you're no longer serving my interests at that point since that has nothing to do with my experience.

Also, I would like to reward the service-oriented business that provide me the most enjoyment regardless of their 'productivity,' or, to put it another way, my (as a customer) enjoyment is exactly the 'productivity' that should be measured, not how much rent they pay.
