Burgundy UK passport with gold crest

I lost my burgundy UK biometric passport yesterday around 3pm near the Buchanan Street entrance to Glasgow Central Station. It's a standard UK passport, burgundy cover with the gold Royal Coat of Arms, and there's a small crease along the bottom edge plus a faint coffee stain on the back. I really need it back—it's essential for an upcoming trip and contains important travel plans and appointments. If anyone found it, please drop it off at the Glasgow Central Station customer service desk or get in touch; it would mean a lot to me.
