body: A friend of mine posted about how someone keeps stealing her food at work, and I recommended she lace it with some insanely hot hot sauce. Someone else commented that she could be liable for poisoning someone if she did that.
  
  
  The thief is already ignoring written labels saying 'private' and 'do not take this if your name isn't \_\_\_\_'. My assumption would be that this constitutes a warning label, and that she isn't responsible, just like a company isn't responsible if you injure yourself using their product in a manner inconsistent with their instructions. 
  
  
  So, I'm wondering:
  
  
  1. Is there any liability at all, since the item in question is being stolen?
  2. Are there any specific legal guidelines for what constitutes a written warning that waives liability for misuse of a product? If so, would this meet those criteria?
