To me the woman sounds extremely cheap, especially when asking the quilt shop owner to copy patterns, which, as you said, violates copyright laws. If you care to share the information, write down the pattern name and where she can purchase it, otherwise tell her that you do not loan any books or patterns (unless it is to a good friend and you know you will get it back, plus she will not abuse the privilege) as you have been burned in the past, in other words, just say NO. I agree with Tartan, if she can afford to attend a quilt retreat, she can afford to purchase a book or pattern.
