You must've ordered something in addition. While I don't know their specific price, I'm pretty certain they're not $21.50 ea.
It could be a two can dine deal or if you added anything to it then the price got knocked up some. Ask for Ernie or Ejay. He is my brother in law and is very helpful.
They are pretty good fajitas.
Maybe it was those 2-4-1 drinks you forgot about?
You got screwed
