Google translate english to Polish
I have mentioned this before but there are other words that BS man could have shouted to Schwartz.
If you put in the word Nosey into Google Translate English to Polish, you get the word
nosy, meddlesome, inquisitive, interfering, pragmatical, pragmatic
If you turn the volume up and click on the speaker you can hear how like Lipski this sounds...
Also I think Lipski is a connected word to a person from Leipzig ? just another thought.
