Customer: “Where do we get the glasses for [film]?”

Me: “Oh, I’m sorry. We don’t have it in 3D here.”

Customer: “What do you mean?”

Me: “Our theater doesn’t have 3D capability, so it’s just in 2D.”

Customer: “What’s 2D?”

Me: “It’s two-dimensional. You know, flat.”

Customer: “I don’t understand. We don’t get glasses?”

Me: “No, it’s just a regular film.”

Customer: “I’m still not getting it.”

Coworker: *overhearing* “It’s not in 3D.”

Customer: “Oh! Okay.”
