As Easy As Pie
(I’m walking in the frozen section when a customer comes up to me.)
Customer: “Excuse me, do you have any pre-made pie crusts?”
Me: “Yes. We have some right here, but also some in dairy right around the corner.”
Customer: “Ah. Do you know the difference between them?”
Me: “One is frozen and one is not?”
Customer: “Okay, thank you.”
