He replied 'I haven't stepped in a supermarket in months, I do all my groceries online. It is much more efficient'.
I have to admit I felt dumb for not optimising my time like he does. But reflecting on it, I feel sad that our private time is becoming a soulless corporate enterprise where everything has to be optimised.
Your private time is just that, yours. I tried doing the over optimizing and in the end, it stressed me out way too much.
I do see human contact in the grocery store... it's between the employees of the store, who know each other, and actually have some sort of relationship, not with the faceless masses that transiently stream through. Of course they don't get to just chat the whole time, but humans being humans, they manage to find some time.
If you choose to value relationships with the people around you then the world doesn't have to have changed very much at all.
My point is, compared to going to the butcher and baker, who are artisans running businesses that are to some extent expressions of theirselves and maybe even their heritage, a supermarket is relatively soulless.
Save the time and do something like dance, art, or sports.
