Texas Stitcher, that shopkeeper was wrong. I may have mentioned in my chat on needlework judges: If they feel the pattern is bad, they assume you lack judgment.
Happened to me twice & they were completely right once. Entered "Two Thai Dancers" from Pinn Stitches. Beautiful, but the faces aren't shaded properly. Go from Ultra Lt Flesh to Med Flesh, which makes an obvious line. Hadn't seen that. Said "Ouch!" When I got the comment sheet.
