It's really too bad Saint Ronnie broke PATCO, because this air traffic controller could use some union support after this insane exchange with a pilot.
But every once in a while, someone wakes up on the wrong side of the runway. My, god, there's another plane six miles away. Reporter: This exchange posted from Atlanta's airport on Friday captures the moment where the pilot is on the wrong taxiway called Lima when he should be on one called Mike.
Supposed to be on Mike. Yes, sir, we're going out there right now. Looks like you joined Lima.
Pilot: We'll taxi out there. I don't like your attitude.
Reporter: The controller coordinating the moment of planes when the busiest airport fires back.
There was no attitude. I'm trying to make sure everybody's doing what I ask them to do. For certain reasons.
Pilot: I make a mistake every two to three minutes but my attitude is not like yours. You didn't tell us how to get there. So next time you can try to do that.
Reporter: One of the pilots listening chimes in with this. Settle down, captain happy.
Reporter: Tonight delta says they are looking into this exchange saying Delta's values call for courtesy and professionalism in everything they do.
Maybe Delta's values call for courtesy and professionalism, but that pilot's don't. Captain Happy owes someone an apology for that conduct.
