Well if you are a tourist they charge you 200-300% extra haha
Especially if you take taxi to like Stare Miasto in Wawa. Then you have to know some Polish voc. to tell him what you think about it.
where you come from (sweden) everything is like 300% more expensive
Actually, some things are more expensive in PL than in Sweden. Eg. some electronics, imported food, jeans etc.
If you want to go to an expensive country, go to Norway, one of most expensive countries in the world. Totally crazy prices.
