Yes, my mistake - it's been a while! Definitely a local thing, and always with German pronunciation. There were a several words/phrases like that which got loaned into English. Doubly confusing because it wasn't always clear if the new word was Züri, regular Swiss-German, French but not Swiss-German, or High German. Had to be careful using new vocab in Germany!

Not to mention that the locals here when referring to it while speaking English, totally translate it to "eɪʧ biː" sometimes.

Other times, in the middle English sentence, the German pronunciation pops up "ˈhaː ˈbeː"

Fun
