Airline Jerks

So im walking into the airport and I see every airline check-in aside from mine (im looking for ATA). I walk up to the Jet Blue desk and ask the guy if I can check in here because I dont see ATA anywhere. He looks at me and laughs (scoffs even) and then proceeds to say in a really condescending voice "Heh, um... if you wanted to return something to Macys, would you go to Nordstrom?" I just looked at him in utter disbelief and then I said "Was that really fucking necessary? I dont see the ATA check-in ANYWHERE. And now I still dont know where it is, no thanks to you." And he just glared at me. THATS IT! Some lady overheard and pointed me in the right direction.. Which I might add was WAY up the hall and around the bend, NOT near any other check-in. So its not like my original question was at all unwarranted. Jerk!
