Blue UK passport with coffee stain

I was wandering around Bath yesterday around 3pm and I must have dropped my blue UK passport somewhere between the Bath Spa train station forecourt and Pulteney Bridge. It's the standard blue passport, a bit worn from travel, with a coffee stain on the cover and a small crease on the bottom-right corner. The inside page is still intact, but I’m really anxious because I’ve got a trip next week and I need it back. If someone found it, I’d be incredibly grateful to arrange a safe handover at the Bath City Council Lost & Found or meet up somewhere convenient in central Bath.
