I always get frustrated when I get to my gate in the AM at one of our hubs and have to wait for the gate agent to show up and check my ID before going to the airplane. When I get verified and go down, there are catering crews and cleaners walking all over the aircraft that haven't even been through security. They're ok being on the aircraft but I have to wait for a gate agent to check me out and make sure it's ok for me to go down.
