'Just have to add my two cents worth here. There are no rude quilters. Quilters quilt to change their attitudes, and it works! We're all wonderful, mild mannered fabric fondlers.
I suspect the lady (sic) you encountered had been dispatched to run an errand she didn't want to do, so she let her hateful nature show. Bully for you for being a lady and letting it go. As I said before...Quilters quilt to change their attitudes so she can't be a quilter!
P.S.
'Sorry your shopping expedition was a dissappointment, but share with us anyway. We love to see new toys!
