Shoplifting Allowed? What is this world coming to?

A few weeks ago, I went to a Duane Reade in Brooklyn, NY.  I was in search of Zyrtec for my allergies.  When I was in the aisle, I noticed a clerk that worked there.  I asked her where the Zyrtec was? She said about 10 minutes ago, she saw a woman stealing it as she put the last box in her purse.  I looked at this clerk as if she had two heads and questioned her as to why she didn't stop her.  She said she is not allowed to do anything.  She can say something, but cannot apprehend someone or call the police.  I walked out of Duane Reade without my Zyrtec in disgrace.  I can't believe what this world has come to.
