(I am working as a cashier and two customers come in talking loudly about how dumb minimum wage fast-food workers are. One of them decides to prove it…)

Customer: “Let me ask you a question. What’s 7 times 7?”

Me: “49.”

Customer: “What’s 8 times 8?”

Me: “64.”

Customer: “E equals MC squared?”

Me: “What about it?”

Customer: “What does it mean?”

Me: “Energy equals mass times the speed of light squared.”

Customer: “Uhm…”

Me: “Would you like fries with that?”
