I lived inside a IKEA catalogue for two weeks once.
(It was a holiday home in NL, actually. Brand new, we were the first batch of occupants ever - and everything inside was IKEA, from the furniture to the cutlery. Everything. Stepping through the front door felt like stepping inside a VR catalogue, and the feeling didn’t wear off.)
I think the “equipment” (along with ceiling, tables, and possibly other patrons) are represented by all the ‘busy work’ Hopper shows in the window reflection. Automat walls (at least the ones in the US and at the time represented) are pretty much made up of the vending apparatus itself.
