White ceramic mug with blue floral rim

I found a white ceramic coffee mug this morning around 9:15 am in the parking lot behind the Whole Foods Market on Fruitville Road, right in Sarasota in the Sarasota-Bradenton area. It’s about 3.5 inches tall with a glossy glaze and a blue floral pattern circling the rim. The handle has a tiny chip on the outer edge, and there’s a faint coffee stain on the inside near the lip. On the bottom there’s a small faded stamp reading 'Harbor Lane'—a nice identifying feature that might help. I figured someone might be looking for it after their morning shop, so here it is. If it’s yours, we can meet up nearby to return it.
