[Zope] Permissions with object container ZClass

I have a ZClass that contains one TinyTable when its instanciated. I have a DTML method that queries that TinyTable. When I access this method using the manager role all is fine, however when I use Anonymous it asks for permission. I don't want to give the Anonymous user Query Tiny Table permission however if I give the DTML method proxy permission of Manager it says I'm unauthorized. How can I get this to work?
