Very good catch ! Zimne Piwo is correct ... I'm 1/2 Polish American ... I had some gentlemen from Poland working at my business years ago and they were helping me with my Polish and vice versa ... In an effort to get my pronunciation closer to correct they would spell some words phonetically. As you may know, Z is pronounced sort of like GZH ... It just stuck.
