They Need A Diet Coke Break, Break

Me: “Hi, welcome to [Restaurant]. What can I get you to drink?”

Customer: “Can I get a diet Coke with extra caffeine?”

Me: “You want me to put extra caffeine in your diet Coke?”

(The customer looks at me as if I’m an idiot.)

Customer: “Yes! Just put the extra caffeine in my drink!”

(I ended up just giving her a regular diet coke.)
