You're right about people stealing anything. At a national quilt show a couple of years ago two "ladies" were looking through a quilting book - at least that's what it looked like they were doing. In reality one was downloading the book, page by page, on her cell phone while her friend held out the pages. SOME NERVE!! I did rat them out to the vendor and she watched for them to do it again, but I don't know if she caught them.
