Lost general admission concert ticket printed on white paper from Dunkin' Donuts Center, Rhode Island.

I misplaced my ticket for a concert that took place last Saturday at the Dunkin' Donuts Center in Rhode Island. It was a general admission ticket printed on white paper. I'm really hoping to find it because it was a birthday gift, and I can't remember where I last had it. If anyone has seen it or picked it up, I would really appreciate a message!
