About 10 years ago I went on a service call. Customer complained that the receptacle serving her living room television was not working. The first thing I noticed was no ceiling mounted light was present in the room. But just for giggles I decided to check for a tripped circuit breaker. Nothing was tripped so I asked the customer what each switch did in the living room. One was foyer light, another for outdoor coach lamp, and the third was for?

Yup, u guessed it, a switched receptacle was turned off!

Lady wanted to know if she would be charged for this "simple" service call. LOL
