I hope the mods punish that thead hijacker :becky:
I do think judges will mark you based on the overall impressions they have of the box. They might not specifically mark down for the garnish, but if it conveys an overall impression of a sloppy box, expect to get dinged for it.
(I have also gotten 2 comment cards saying my meat was too cold, and KCBS says you aren't supposed to judge on that...so I certainly wouldn't rely on the expectation that all six judges will know and strictly follow the rules.)
