You haven’t owned coffee places. You’ve been entirely wrong on how to source coffee plus your description of what even makes coffee. If you used to own them, you probably ran them into the ground. You’re objectively wrong on coffee production.

Peet’s had 4 stores before it started changing hands, Peet’s and Starbucks famously did not compete with each other for years, and Starbucks wasn’t even selling brewed coffee before it was taken over by Shultz and venture capital.

But from my experience in the industry, your confident incorrectness is perfectly in character for a coffee shop owner.
