Even with group interviews... Let's take the supposed profit, 300$, and assume it's 100 pops at 3$ each, and for the sake of it let's say revenue = profit in this case. That's 100 purchases per day.
The post claims 50 interviewees per day, so 2 purchases per interviewees.
By groups of 10, that's 5 cohorts spending 1h each with the interviewer, during which every. Single. Person. Buys 2 drinks?
Humm!
And it would certainly help explain the state of the world, if the simulation had to divert more and more power to quantum physics and cosmological math, no cpu left for, you know, "people" to be intelligent..
Mfw we realize we live in a Rick and Morty episode...
