My family hosted a Soviet exchange student in 1989. It was a last-minute host switch, as the girl's original host family had to relocate for a work transfer. So my parents didn't get the training about what to expect, or culture shock, or any of that. They went in blind.
When she arrived, we picked her up at the airport and then went to the grocery store to pick up dinner. It was a big store, though not a fancy one. It was a Cub Foods, one of those places where the toilet paper was stacked sky-high in the warehouse-like aisles. When we entered, she got visibly uncomfortable. Then she seemed almost angry. She asked my parents, in a skeptical/harsh voice, "who is allowed to shop here?" My parents told her "anyone," but she didn't believe it until she saw how weird I found the question, and I was too little to prop up a lie that well.
When she realized we were telling the truth, and that this wasn't just a store for apparatchiks but actually wasn't even the best grocery store in our two-grocery-store town, she sobbed howling sobs in the toilet paper aisle, the rolls stacked up to the ceiling.
Anyway, that's why I've never been tempted by communism.
