The best way for a Polish person to learn English? [46]
You actually have a point. It cuts both ways too. Anglos wanting to learn a foreign language abroad in recent years (pre-Covid, of course) are often met with a slew of well-intentioned folks eager to barrage them with broken English while usually unwilling to concede to the simple fact that plenty of Anglophones might know their language more competently than the foreigner knows English:-)
Anybody with close caption capabilities on their phone or home PC can readily turn on or off the English captions at the bottom of the screen. This technique works for all languages.
