Thats shocking - how dare she eat at the gate or infact eat at all
the fact shes might be double shift covering for someone who didnt come in or didnt get a break because shes been sent from gate to gate is irreleveant due to staff shortage or some other unseen reason,
yes granted she should have stopped and answered your questions which 99% of the time you are either asking the wrong person, wrong handling agent, not looking at the screens correctly, or not thinking "how can i help myself without bothering this poor person"
what was wrong, couldnt you look at the screens for you flight, ahh of course it wasnt listed (how many times have i heard that !!) or lost your way ? look at teh big signs above the gates they have numbers and/or letters usually in a sequence.
These monitors around the airport are a wealth of info, next time have a look at them and stop bothering staff.
sorry, dont see your problem !!
(if you wanted a bite, you shoul have just asked her, she might have shared !"
