Well here is where my PhD in tracking stuff on paper, which gets handed out in triplicate to every German child at birth, comes in handy. The signature line customarily includes the date again because printing date and signing date (and thus validity) might differ. And yes, I know this is not applicable in a restaurant (hopefully), but that’s generally the reason when it occurs.
