but will you understand "f** off" in Lithuanian?
No but I bet my bottom dollar Ryanair employ a lot of people who know that. As I said before, the English of one UK domestic crew was so bad the passengers laughed all the way through the safety demo. We thought they were parodying Borat in all honesty. There is no way there was any confidence in that crew believe me.
Good to know you advocate slyly swearing at your customers in a foreign launguage. That's classy, really.
