Funny you asked this, because I'm still irked at the way my LQS cuts their very expensive fabrics ($10/yd and up). They use a formica topped counter and a yardstick to measure, then cut with no guideline whatsoever.
JoAnn and Ben Franklin stores -- both of which I think of for finding less expensive fabrics -- have the formica tops with a steel ditch to guide their scissors while cutting.
Needless to say, I won't be buying from that LQS unless I absolutely have to. I think part of my irritation is that they think they're doing you a great big favor with a very rare 10% discount.
