Regarding the new McD’s look, I was just in one a few weeks ago, brand new location, and it really was grim. Very much a dystopian look.
Very short counter with one register (no worker present), two ordering kiosks, a bench on one side, two small tables, and a shelving area for DoorDash pickup.
The lighting was that really uncomfortable 1970’s fluorescent stuff, but the weirdest thing was the lack of people. I was the only customer. No visible workers. I ordered and paid at the kiosk, put my number down on the table, went to use the restroom, and there was my food. I never saw another human the entire time I was there. Very surreal.
I ate without drinking anything because I usually ask for a cup of water from the counter, but no one was there and it wasn’t open to the kitchen area.
