Is it just me or does she say "skapety" instead of "skarpety"? Is it intended?
The 'r' is very, very vague, true. But no, it's not intended. In Polish, you could count on your fingers the words in which some letter is not pronounced on purpose. "jabłko", "pięćdziesiąt", "sześćdziesiąt", "dziewięćdziesiąt" (and their forms)... I don't know what else.
