Polonia /
Polish workers in Denmark [41]
I can attest as someone who lives in the US, that Polish workmen are proverbially reliable, diligent, and honest, their foreign-language speaking skills notwithstanding:-)
They typically work solely on a cash-only basis and probably know limited English, although as many Danes know English, little reason for the former to know Danish except perhaps for the basics of "yes", "no", "thank you" etc.
Do recall the amusing, probably typical, incident whereby a Pole asks their Danish boss a simple yes or no question, to which the latter responds with "Ja, tak!" (lit. "Yes, thank you!), leaving the Poles momentarily confused, since in Polish of course, "tak" means "yes", not "thank you", and "ja" mean "I", rather than "yes"LOL
