Thanks all! I was probably thinking of the NM issue and confusing it with PHX. I'm based in the northeast--all those square states out west start to blend together after a while.
I guess I'll just chalk it up to the FA being lazy--the flight was not running late and had boarded fully well before departure time.
Perhaps the flight attendant just forgot or just was being lazy.
She definitely didn't "forget." I asked for a beer when she had a tray of water and the gruffly said "no" and stormed away. She would even let me ask a follow-up question she ran away so quickly!
