I am not a programmer, not a geek, but just the ability to recognize problems and then find and implement the solution gives me the aura of an omniscient wizard. Simple things like: We have an automatic drying machine for work clothes here, but we haven't been able to use it for YEARS! A Google search, manual found. We now have the third coffee machine. They always break because of the chalky water. When we descale, the display still lights up: If I really go through the instructions in the manual step by step, it suddenly works. And that's before we get to any multiple screens or Excel problems with the sum function.
If you can interpret your car's manual, you're a hero. If you can also get hold of the vehicle's repair manual, then you're a wizard. And if you understand the sum function in Excel, then you are a danger to your supervisor.
However, this assumes that the customer knows what the brand names "Barbie" and "Hot Wheels" stand for. Perhaps she just had to bring such a menu of toys to a boy and didn't have the cultural knowledge behind the terms. It would have been helpful: A doll or a toy car?
