The MCO peons peeving those in this thread, are airport services contract personnel. Since they tend to hang around and assist the CLEAR pax through the lines, I long thought they were Clear contractors, but I may be wrong about this.
They do natter on and on about which line you should be in, but in IME you you can ignore them without any penalty other than the increased buzzing as they are faced with the reality of how pointless their non-function is.
Their core responsibility seems to be ensuring that no non-employees get in the employee security line, even if that line is completely empty.
I don't know why MCO can't get its act together like TPA and have these people perform a dual ID check.
Recheck ID's before getting on the monorail. Then the airport is clearly twice as safe.
