They just don't even try to give customer service. Bad enough the food is over priced my wife spent 40 minutes waiting for burgers to have them finally tell her they were out of burgers. I walked up to get a drink and though there was nobody in line at all I waited 5 minutes while the two girls working the registers talked about boyfriends. I finally just asked if they were ignoring me for a reason and the reply I got was an annoyed "Well what do you want?"
Honestly if they suck at providing food they should allow you to bring your own.
