A customer at the Modern Taco Company at Grant Park Shopping Centre brazenly stole a smartphone left on a table by manager Morgan Wowk on Sunday.

What the woman didn't know is that both the theft and the image of her taking it was caught on the restaurant's surveillance camera.

"Yeah, it sucks," Wowk said Wednesday. "But I'm pretty confident that I'll get it back."

That's because the woman also paid for her purchase with a debit card. That information has been turned over to the police along with the video footage.

"I gave the police the transaction, and I'm pretty sure they can track her down that way," Wowk said. "I'd never seen her before ... She looks like she's fairly well off, so I don't know why she would take my phone. Some people have said she might be a kleptomaniac."

Wowk also posted the video to YouTube.

Wowk had left the $615 phone beside his open laptop on the table near the ordering counter.

"It was pretty upsetting," he said, adding his phone is not password protected.

"She will have access to my contacts and pictures and Facebook," Wowk said. "I could block her from using Facebook, but I sent her a Facebook message on it instead."

Wowk is now warning others to be more careful about leaving such personal items unattended.

"I told everyone about it," he said. "That was one bad habit I had, for sure."
