It's basically a resignation to what capitalism is trying to sell you- units of something, you become a statistic, it's not the enjoyment of the food, it's about a sterile transaction between patron and chef, where you get so and so filled to such and such a degree, and that has some specific arbitrary value in money.
It's just such a consumer zombie way of perceiving the world, I just can't.
