UK passport with burgundy cover and travel sticker

I lost my UK passport yesterday around 5pm outside Brighton Station on Queen's Road. It's a burgundy passport that's a bit worn, with a small coffee stain on the bottom-right of the front cover. I also stuck a tiny Edinburgh trip sticker on the back cover, which is a pretty distinctive giveaway. I really need it back because I have a visa appointment next week and a summer trip coming up, so if you found it, let's meet at a nearby cafe near the station to sort it out.
