Red Ticketmaster concert ticket for tonight in Manchester

I lost my red, credit-card-sized Ticketmaster concert ticket yesterday around 3pm outside Piccadilly Gardens near the Arndale Centre on Market Street. The ticket is glossy red with a holographic Ticketmaster logo in the corner and a barcode ending 4832; there’s a small orange sticker with my initials 'AP' on the back and a slightly creased bottom edge. The seat is in section A, row B, seat 12, and it’s for a show I was really looking forward to — it was a gift from my sister and has sentimental value. If anyone finds it, I’d be incredibly grateful to get it back; I can meet up in central Manchester to collect it.
