then be denied it's check-out due to ageRestriction.

This patch prevents reserving material for borrowers not suitably aged.

5. Check-in an Item from the ageRestricted Record and catch the reservation.
6. Check-out the ageRestricted Item for this underage Borrower.
7. You get a notification about being unable to check-out due to age restriction.
