In a situation like that, first ask to try the biometric scanner again. In some cases, the biometric scanner will work the 2nd time when it didn't work the 1st. As far as the CM being peeved about accepting your ID, I don't know why they would be. The only answer I can give is that they were having a bad day. CMs are told that a photo ID is the backup identification if the biometric scanner doesn't work (and I assumed this to be true, regardless of whether or not a guest has been in a park earlier today)
I read the original post as that the AP went through and the biometric scan succeeded but the CM still asked to see a hand stamp.
The idea here is to make it so it is difficult to get in without having purchased admission.
If the ticket says that it has not been in a park yet today, then it just lets you in.
If the ticket says that it has been in a park today, then the bearer must have a hand stamp to get in with it.
So if two people go in with tickets and one of them leaves with both tickets (one of them staying inside the park) then they won't be able to give the ticket to a third person to gain admission because that third person doesn't have a hand stamp and the ticket said it was already in a park today.
To get in with a "used" ticket you must have a hand stamp which you can only get inside the park (on your way out but it is still inside) which you had to pay admission to get in to.
Of course, there are times when you "forget" to get a hand stamp but you still manage to get in another park without any trouble. It depends on the CM checking the hand stamps. Perhaps they are backed up at the turnstiles and they would rather risk letting some folks in when they shouldn't than hold everyone up. But the idea is to deter folks from trying. You could be denied entry if you don't have the stamp.
So, now the questions....
What if you manage to preserve your handstamp from yesterday? Will you be able to get into a park on someone else's used ticket? Are the stamps from day to day discernible enough for yesterday's stamp not to work today? Like the previous poster asked, won't the previous day's stamp muck up today's stamp so you're left with nothing but a glowing blob under black light?
What if you don't have hands or they are in a state such that they can't be stamped? How does that work?
