body: A convenience store clerk refused to sell me tobacco when I declined her request to scan my ID. I did allow her to inspect my picture ID which clearly showed my age to be 63 (as if she couldn't tell by my degenerative condition). She stated it was now state law that everyone gets scanned in California. I can find no such law. No store has requested my ID since. 
  My question is:
  Do I have the right to demand proof of a law which I believe to be non-existent or interpreted wrong?
  
  
  
title: If a retailer refuses to sell an item citing a state law are they required to prove the legitimacy of the law?
