Lost black leather travel wallet and passport holder last weekend, possibly left at a restaurant in Leonardtown, St. Mary's County.

I lost my black leather travel wallet that also serves as a passport holder while I was visiting St. Mary's County last weekend. I think I may have left it at a restaurant in Leonardtown. It contains my passport, several credit cards, and some travel documents. I'm really worried about losing these important items, so any leads would be greatly appreciated!
