I think it varies from place to place. I do know that I would put back everything that I was purchasing if I was told to leave, even if I had finished paying for it. That is one sell they would loose. We should start boycotting stores!!! Yeah!! Let our babies in! Anyway I have never had a problem from anyone but Walmart, and yet people can beg money(not referring to Salvation army and such) from you when you go in and out, I find that more annoying than seeing a pet in there.
