(A fairly regular customer, known for asking lots of questions about merchandise he had no intent of buying, wanders in to the electronic department.)

Customer: “What’s this?”

Me: “It lets you browse the internet on your TV instead of requiring a computer.”

Customer: *excited* “Really? Wow!”

Me: “Yep, and if you buy the optional keyboard, you can even use mit for email.”

Customer: “Email? I’ve heard a lot about that. What is it, exactly?”

Me: “Well, it’s kind of like regular mail. You type up a letter and send it off,
except it gets there instantly and there’s no postage.”

Customer: “Really? Wow! Does it do packages?”
