Silly Things I've Done #6

At nearby McDonald outlet

Me: "Can I have McChicken Wings meal, please?"
Cashier: "Sure. What would you like to drink?"
Me: "Sprite, please."
Cashier: "Do you want to upsize?"
Me: "No."
Cashier: "OK. Eat here or take away?"
Me: "Take away. Can I change the fries to seaweed shaker fries?"
Cashier: "I'm sorry, no.. If you want it, you have to @#$!@##$&*"
Me: (Thinking that @#$!@##$&* was spoken in Chinese) "I'm sorry, can you speak in English?"
Cashier: "I AM speaking English. I was saying, if you want the shaker fries, you have to upsize your meal. Do you understand what I'm saying?"
Me: "Perfectly clear, Sir."
(Drat, I shouldn't eat that muscle relaxant pill and going around talking to people...)
