There is nothing wrong with membership in a social GLO and a service GLO. That is not "dual membership" in the sense that we are discussing in this thread. As for violating a service GLO's "lifetime commitment", not every chapter of service GLOs teach "lifetime commitment". Those that do will have difficulty overcoming the varying cultures. If someone has always been told a service GLO is a club to join to get more involved in the community but nothing more longterm and dedicated than that, there will be people who will view a service GLO as transitional.

ETA: That doesn't mean none of these people did community service before joining the service GLO. Some people join service GLOs because they love service and want to further their community service. When I was interested in joining APO it was after years of community service in high school and college. I ended up not joining for a number of reasons but some of the members of that APO chapter expressed a lifetime commitment to service but not necessarily a lifetime commitment to APO as an organization.
