Wow. Thank you. That's a wonderful story and jives both with my lived experience as well as that key missing piece of "head-cache" transparency in the system.

I also just realized they use this method at one of our local coffee-shops (Boxcar https://boulderdowntown.com/go/boxcar-coffee-roasters ).

It's a shame they've decided it wasn't worth the additional training-hours and shrinkage to continue the practice.
