The worst are the ambassador (concierges) that hold your print boarding pass hostage whilst they wait for their computer to update with the needless flight and gate information.

This is another Delta service that should have died with the advent of the smart phone. The passenger’s access to information at many times can be far superior to the SkyClub’s. I’ll see on FlightAware and TripIt, gate changes before some of the airline’s own 700+ points of interface to their network share it with their staff.
