Do the former if you need to implement different behavior.  Do the latter
if Customer already provides the needed interface for a requester.  Be
careful, however, that you do not mix the interface of Customer and
Requester, but have clearly defined them seperately (even if both
interfaces may share a method, or one interface is derived from the other.)

Yes, it would be necessary for you to add the property, since Zope security
ordinarily frowns on setting arbitrary object attributes.  :)
