You’re right. I can remember when many Sears stores still had their diner/snack counters too. Sears sold just about everything a middle class family needed back in the 1960s and 70s.
The Last few times I was in a Sears store I was shocked at how empty they all were. When I was young - and I worked in one when I was a teenager - they were always busy.
I still get my car battery at Sears (Die Hard Gold) every 4 years. Best car battery I’ve ever used.
