Should you keep their card?

QUESTION:

 

When someone presents another person's card as their own can we keep them?

 

ANSWER:

 

Yes, but don't get confrontational about it.  Either way you need to put a block on the ID to indicate that the patron is required to show his/her ID in order to use the card due to it being used by another patron.  Use common sense regarding the situations to which this should apply.  For example, this should obviously not apply to a child with a parent's card, babysitter with parent's card, etc.
