Pair of concert tickets with teal border

I found a pair of concert tickets this afternoon around 2:15pm on the sidewalk outside the Fremont Theatre on Monterey Street, San Luis Obispo. The tickets are for a show called Sunset Serenade this Saturday at 7pm, general admission. They're white with a teal border and have a barcode; one ticket has a coffee ring on the corner and both show the name 'Alex Rivera' at the top. I stuck them in my pocket thinking they might be lost by someone smelling of coffee - hopefully the owner sees this and can reclaim them before the show. If you recognize them, I can meet downtown near the City Library or email to verify.
