I would have said something. Through the kindness of others waiting in line at the cutting counter I've learned things I missed and have also helped a new sewer find the things she needed to do a project. For the most part I find that people who work with fabric are pretty nice folks which is also what I find on this board.
I really don't understand why a person who has never sewn a stitch is employed at a fabric store. I asked the other day where I could find the charm packs and I could have been speaking a foreign language, the clerk had no idea what I was talking about. She referred me to the beading section. That isn't fair to the customer and it sure makes it hard for the employee.
