Lost black travel duffel bag with a distinctive red strap and initials J.D. under a table at a coffee shop in Riverside.

I lost my black travel duffel bag with a distinctive red strap while stopping at a coffee shop in Riverside. It has my initials, J.D., stitched on the side. I think I left it under the table when I got up to leave. Inside, there were some important items like my toiletries and a pair of shoes, so I'm really hoping it turns up.
