I am sorry if this message is in the wrong section. I am very mad about something, maybe it has happened to you all. I would just like any feedback you can give me on this subject.

Someone (I think my only competitor in this small town) is stealing my business cards that I am leaving at local businesses around town. I place them on bulletin boards, etc. and in a few days, they are gone along with the pushpin. I have not been getting any calls in this area so I am pretty sure this person is taking them. What in the world can I do to stop this? I am sure there is nothing legally wrong with this, so what steps would you guys take to control this situation? I am just p*ssed, pardon my french.
