I can't help myself sometimes when taking a call from a customer.

Customer: My TV Doesn't work
Me: It won't even power on? Did you call a Electrician?
Customer: It powers on fine:
Me: Oh, I thought you said the TV didn't work. Did you mean you can't see a picture?
Customer: Yes
Me: what happens when you select bluray? Does it work then?
Customer:yes
Me: Unplug the cable box, wait 30 seconds and then plug it back in.
Customer: That worked thanks.
Me: So just for the record, Who was the problem?
Customer: The cable company
Me: Correct. However this call happens to be free of charge today.You are welcome
