I am a giant fucking sturgeon

Saturday night, the blinds are low, 7 or 8 players (no one out), chip stacks about even. Things are called/folded around to me at the button-1, and I raise to 5 with KQo (from a BB of 1). Dealer calls and everyone else folds. Flop comes AAA, and Amanda (the dealer) makes a huge funny face. I have no idea if this means the flop hit her or if it's just in reaction to the 3 Aces, but I figure at worst (for me) she has a pocket pair to my overcards, discounting the possibility that she has the last A, so I get aggressive and go AI. In my mind, I want her to call with a pair smaller than Ks or Qs, and figure that's all she really can call with unless she has the 4th A. So the way I have it figured, I'm either gonna pick up $11+ when she folds or I'm in a coin flip, which I'd be happy to do to get a stack I can finally start being chip bully with. She quickly calls me and I'm feeling okay about things when I turn my KQ over, thinking "yeah, baby, coin flip time". She turns over Ace rag. Fuck me. Drawing dead, no way to hit a straight flush. I'm out of the tourney.

She PW\3D me! Lesson learned.
