Chick-Fil-A
Me: "I'd like a spicy chicken biscuit."
Server:"We don't have those."
Me: "Do you have spicy chicken files?"
Server: "Yes."
Me: "Do you have biscuits?"
Server: "Yes."
Me: "welllllll.... Why don't you put one of those spicy chicken files on a biscuit."
Server: "We can't do that sir. Spicy chicken is for lunch."
That reminds me of the chow hall at IWA way back in the day.
"May I get a patty melt?"
"Sorry, we don't have those on the menu"
"Can you make a burger topped with grilled onions, cheese, and put it on some grilled rye toast?"
"Sure! Coming right up!"
