Sup Chowhounders! I've been lurking around here for a while but never post since most of my questions have been answered before. Anyway i was looking at a few staub fry pans at WS today and they all seemed to be fairly smooth on the inside. But when I got home, the one I bought seems fairly rough. Kind of a sandpaper type feel.I'm pretty sure the demos had a slick feel. Should I return it?
