Count On A Teenager

(I am doing some shopping. I am in the soda aisle, when an older customer comes up to me. I am 18.)

Customer: “Excuse me; I was hoping you could do me a favor. I don’t have a calculator, and I only need one of these.”

(The customer points to sodas marked five for $11.)

Customer: “Could you figure out how much one is?”

Me: “Of course! One is $2.20.”

Customer: *suddenly angry* “If you didn’t want to do it, you could have just said so! There’s no way some stupid teenager like you could figure that out without a calculator! You teenagers can’t even add or subtract without one; how could you possibly work out decimals without one? You just made up a number to get me to go away! I’m on a budget, trying to make sure I have enough to pay for my groceries, and here you are telling me an incorrect number! You could have completely ruined my budget for the rest of the month by making me go over!”

Me: “Ma’am, I’m sorry that you think I was trying to do that to you.”

(I pull out my phone and do the math.)

Me: “The price is still $2.20. But just because you only know stupid teenagers, doesn’t mean you should assume everyone you meet is the same. Might I remind you that you had me do it for you, because you didn’t have a calculator?”
