A grammar nerd question: the sign in the previous post reads "express consent." This is how I've always used it and how I usually see it written, but in the text of the post itself I used "expressed." Which should it be? "Express consent" sounds like something you would do in a hurry or when you only have 10 items or less to consent to. Whereas "expressed consent" sounds like something you have actively done, i.e., you have expressed/articulated your consent.
