Are you able to hear the different English accents? [97]
Anyway, what english accents / dialects have you Polish experienced in your time of meeting English people?
Here's the thing, most Polish people who learn English (in Poland, and some outside Poland) do so purely instrumentally. They are not looking for a new language to use with their nearest and dearest nor a new culture to embrace. They simply want an auxilliary language that isn't too hard to learn and doesn't threaten their national identity and one that will be useful in travel and/or work.
This means that lots of things that interest native speakers (like different accents/dialects, funny word games, slang, etc etc etc) are of no special interest to them. Given that they may transfer attitudes toward Polish to English they may regard anything that's not "standard English" as being of questionable value and their idea of 'standard English' is liable to resemble the BBC in the 1970s.
There are individual exceptions but that's the general case. Also accents (except the broadest) are always harder to distinguish for non-native users than for natives.
Also, as I've mentioned before, most Americans (like me) can't tell most British accents apart (they can distinguish very broad Scottish, Cockney (is that still a thing?), something like RP and Irish.... and that's about it.
At a conference recently I heard a question from an attendee from Northern England and I only understood about 60% or so (and that was mostly the polite introductions to his real question). I have no idea what non-native speakers made of it.... One and one I was able to converse with him but not without a lot of "excuse me?"s and "huh?"s thrown in on my part....
