I just saw one of these guys, different scenario. Local grocery store controls the flow of pedestrians so there is one distinct 'exit' and one distinct 'entrance'. When you go in, they give you a buggy that's been sanitized for your protection.
Everything is clearly laid out and labeled with signs with enough workers to assist.
Guy in his late 50's early 60's tried to go in the exit. Security guard stopped him. "What is all this crap? I just want to shop". He was politely directed to the entrance line (five people long), and he just barged past everyone. Again security stopped him. Again he said he 'just wanted to shop'. With a little assistance, he made it inside.
I was kinda watching him as he made his way around the store. He seemed 'off' to me. Watching his actions, he seemed to be having a hard time grasping what he was seeing.
Then he got to a check out lane...........
The cashiers for the check out lanes are behind Plexiglas now. I was too far away to hear the convo, but he thumped the plexi, flailed his arms around and stormed off once he got his groceries.
Security watched him leave.
