A client calls into our Help Desk line:
Client: I just got a laptop here and want to take it home to do some work but I don't have a charger.
Me: What happened to the charger?
Client: I just never got one, I figured it would be in the bag but it wasn't there.
Me: OK, let me see...
*I check and see that she got the laptop over 2 months ago*
Me: Have you been doing work on this laptop?
Me: How have you been using it up until now?
Client: Well...it's plugged in.
Me: That would be your charger ma'am
