Lost black leather phone case containing an iPhone and important cards near a café on Pearl Street in Sioux City.

I left my black leather phone case at the café near Pearl Street while I was having coffee with a friend. It has my iPhone inside and some important cards. I realized it was missing as soon as I got home, and I've retraced my steps multiple times but haven’t found it. If anyone has seen it or picked it up, I’d really appreciate getting it back!
