I work in corporate event production.

Me: Will you need content on the screen this afternoon?

Client: Nope!

Me: Okay great. So we’ll just run audio.

Client: Yep, just audio and the laptop.

Me: You mean, you need the laptop display on the screen?

Client; Yep. Just the audio.

Me: And the laptop on the screen?

Client: Yeah, I guess that makes sense.
