Although logical, this would not be a defense to serving a minor. Even if she washed the mark off entirely, had a fake ID, the liability is still there -regulatory liability and possible criminal charges. We actually saw this in a different high profile case, a long time ago. The Girls Gone Wild creator Joe Francis filmed underage girls, inside a nightclub, drinking and exposing themselves. Joe's defense was that the bar had a 21+ rule and he could assume the girls inside were all 21+. The defense particularly worked for Joe, who was later convicted of not maintaining porn ID laws, but the bar was subsequently held liable.
