I have no idea what grocery store you frequent, but my produce section could go on about cabbage carving do's and don't's for an hour at minimum. Speak directly to that person's manager. In any case, you evidently managed quite well, despite such limited guidance by the purported 'experts'. Bravo, and welcome.
