"Nie, dzięki."

Translation: No, thanks.

"Jenky" (Dzieki) may be my favorite word so far.

[Jillianimal]

It sounds like there's an N in dzieki. Would you normally hear that when Poles talk?

[kamrelim]

It depends, in more casual conversation sometimes ę may get "shortened" and sound like 'en'.

[oliwialolgajor]

i am polish so can explain to u. the e with a "tail" gives it a en sound

[br0d4]

With hyper-correct pronunciation (like in a theatre) - no. But often in everyday conversations.

I heard that saying dzieki as opposed to dziekuje can be considered rude in certain contexts... like sarcasm almost so to be careful when to use this, is this true does anyone know and how can one know?

[Thallion]

yes, my friend is polish native speaker and he also told me not use dzieki in public like at the restaurant or with people you do not know well because it is rude. and his friends also agreed with this statement.
