This is why we do an important step when we design holiday lighting. When we determine which outlets we will be using, particularly when they're in a garage or shed, I always shut off that circuit and test the other outlets to determine which ones are also on that circuit. Knowing you designed the lighting to 90% capacity does little good when there is a fridge or garage tools on the circuit.
I would say a lot of blame rest on your shoulders. When she called you, did she volunteer "a few lights are out", did you ask if it was a few bulbs? a full string? did you ask point blank if it was a section of lights (portion of house, a whole tree). You have been doing this property for 10 years, you should know it like the back of your hand. You have a history of designing the system to the point that you routinely pop the breaker, how was that not your assumption when you got the call?
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
