Do you hear people speaking this way? Is it considered socially acceptable? How do speakers of standard Polish react to it: with interest, amusement, disgust or indifference?
Most of polish dialects are rural dialects, and are a little bit stigmatized. I know that it is a little different in the UK, where the rural dialects are perceived as picturesque, worm and homely. In Poland people that use those dialects are usually perceived as uneducated peasants. Things are a little different with Silesian, Kashub and Gooral dialects and with accents on the whole though.
I would also like to add that I do see a slight change in those attitudes. My uncle started to ask for “pyry” when buying potatoes recently even though he used to consider it a peasant talk.
-edit- Ok, when I wrote accent in this sentence: " Things are a little different with Silesian, Kashub and Gooral dialects and with accents on the whole though.
I actually meant intonation.
