People are sneaky, but you have to get creative. Once I talked about the chicken I had made me sick, said I was fixin to throw it out. Instead later, I ate it, no one touched it. But you cant use that line again or they know you're fibbing. I make sure it is not appealing to others. Crunched up aluminum foil, tore up labels on drinks. One time I was mad and wrote on a soda bottle, after tearing the paper label off a little, and wrote with a black marker ' POISON Do u feel lucky today?!! But some people will steal anyway.
