Over the past few years, I have repeatedly had the batteries stolen from electronic devises in my condos. The worst is the remote controls for the TVs. People will literally take every battery from every remote! Then the next guest sends me an angry message, and because I'm not local, it is difficult and expensive to deliver new ones. Being that I don't feel it's my duty to provide unlimited batteries in a drawer for people to steal, I'm hoping someone may have a way to keep guests' sticky fingers away from my batteries. Any thoughts? I hate the thought of leaving a sign threatening to charge, so any alternatives would be greatly appreciated!
