Red Ticketmaster concert ticket stub

I lost a red Ticketmaster concert ticket stub yesterday around 3pm near the Starbucks inside the Columbia Center Mall on Columbia Center Boulevard in Kennewick. The ticket is about 2x4 inches, red with white print, and it has a perforated left edge; there’s a blue VIP sticker on the back with seat details: Section B, Row 6, Seat 12. It’s a bit crumpled and has a coffee stain along the bottom, plus a faint crease through the middle. This ticket was a gift from my sister and we were supposed to go to the show together, so it feels really sentimental and I’d be incredibly grateful to have it back.
