I have seen the same thing and not only that......I was checking out with a stack of fabric and this clerk started looking through it and said to me "I need to make sure you're not stealing anything" That really made me made so the next couple of days I went back because I couldn't get this off my mind and I asked for the store manager, he came over to me and I told him what had happened and he looked surprised and wanted to know who the clerk was and I told him. I told him this had happened before but with that clerk she was nicer about it, she just said "I need to make sure you got everything".
That store is really begining to bug me.
