The LAX CO staff are among the best in the system, they really go out of the way to be welcoming and helpful.
I cannot say the same about the TSA staff as from time to time they can be bark just as loud as their counter-parts at EWR and also share their shoe fetish from time to time.(Which really drives me nuts as their polcies seem to change like the wind, sometimes shoes on/sometimes shoes off/sometimes boarding passes out/sometimes not.)
Granted the terminal is not the world's best but the PClub is nice and people there make the less wonderful terminal acceptable.
