Why are gate agents so moody all the time? I recall a time when I was trying to non-rev from point A to point B and the gate agent couldn't find my name in the system and I tried to make a recommendation and she started literally making a scene in front of all of the passengers! Has anyone else had similar experiences or am I the only one that has been verbally assaulted by a gate agent

? To me it always seems like a gamble with them, they are either irate or very friendly, no in between. All gate agent terror stories are welcome!
