When will she learn?

The nature of our job involves a lot of coordination. Those people who do voice-overs for us and usually DJs, and they have to go on-air at specific time slots. It is always easier to text them, than call them as they might be doing some voice recording and will not be able to answer phone calls. After working with them, we would usually take note of the time slot in which they go on-air and avoid calling them at that specific period.

Ah Girl did the unthinkable.

Ah Girl: Hi xxx, is it convenient for you to talk now?
xxx: "i'm on-air now" (something which I figure it out later)
Ah Girl: I know, that's why I ask you whether is it convenient to talk now
xxx: .......
Ah Girl: Are you able to come down to do a voice over?

At this point of time, I almost fainted. I forgot what happen later.
