I worked in a call center for a well known cable/broadband provider when an older woman calls about her TV not working properly.

Client: “I cannot get a picture on my TV.”

Me: “Is it just black, or are there some numbers or text on the screen?”

Client: “No picture, but I can see the clock telling me what time it is.”

Me: “Ok, there should be some buttons on the side where you can change the channel or input. Do you see those buttons?”

Client: “I don’t see anything about channel, but there are buttons.”

Me: “What buttons do you see?”

Client: “Well, I see Time, Start/Stop and Defrost…”

Me: “Ma’am, are you looking at your microwave?”

Client: “…Oh dear. I hope not.”
