(A customer comes to pick up a phone they had dropped off for repair.)

Customer: “I’m so glad it is working! What was the problem?”

Me: “It just needed to be charged.”

Customer: “No, it was fully charged Friday and then just died.  There must be something else wrong with it. Please look at it further.”

Me: “Well I did. The battery was at 0%, in fact, you still will need to charge it for quite a while. It is working though.”

Customer: “No, you keep it and keep looking.” *leaves*

(The customer comes back two hours later. A co-worker handles it.)

Customer: “So is it okay?”

Coworker: “Yes, it turns out there was a problem with the phone’s N.R.G. We have corrected it.”

Customer: “So that explains it!”
