i think possibly a reason for this is at the start of every new season, new temps are recruited and maybe a little over keen at first as are new check-in staff weighing your handbaggage to the nearest lbs...i may be wrong
respect works both ways but not in this case
some crew when walking threw sometimes are very nose in the air when walking past the security staff at the check point making them feel like low-lifes...maybe this guy had experienced it a few times and although wrongly tarred all crew with the same brush....i think we may have to allow a little not so much understanding for him being like he was but look into possibly WHY..
my opinion only.
