Most non-restaurant stores are closed in Poland on Sundays. At first I found it a bit inconvenient, but as I've lived here longer (going on ten years) I really appreciate it. It's a forced "slow down" day that's society-wide. It also helps push back against the constant desire to inject money and capital into every aspect of life.

It would never be allowed in the US, but I do think a designated "don't buy stuff" day once a week would be a really good idea, as well.
