Trust me, when it comes to complaining about trivial things, you can't beat the Dutch. They live in this incredibly well run country but still complain about everything all the time. It's crazy. Oh, wait...

Ex-communist probably. Romanians also like to complain. I think it's what people do when they feel powerless. They don't see what else to do other than complaining. Problem is you tend to complain even when you could do something about it.

Definitely a side effect of communism, you can see how different it was if you read older literature, newspapers etc. The comparison can be made between Eastern and Western Germans.

Post-communist rather. Romanians also complain a lot, the grass is always greener in the neighbour's lot, if they do associate they'll most likely screw it up as every person pulls in a different direction (for themselves).

It's quite saddening to read CZ has similar issues. We've been in CZ in 2007 and Prague in 2017. I liked Prague a lot in 2007, not so much after ten years.
