Brothers, how do I catch this paper plate bandit?

The office building I work at has a stack of paper plates in the break room and two weeks ago they were stolen, I asked my co workers but nothing. we thought nothing of it and just bought more and they were stolen again! I tried to do everything I could. We bought more plates and they were stolen again today what should I do?


Perhaps invest in a video camera for the break room. If not that, I suppose an alternative would be to post a notice that, due to theft, the company will no longer be providing supplies like paper plates, etc.
