"Poland:
Maybe not never, but be cautious while getting a cab at the airport/train stations. Most of the guys will try to rip foreigners off.
Also, never leave our country without trying traditional polish cuisine, because it's awesome. I recommend some pierogi, bigos, żurek and zapiekanka."
Kind of goes for the Scandinavian countries too. Best thing about the covid distance of 6 feet being over.... us Norwegians can go back to the usual 12 feet :D
