Opposite direction
Hiring an electrician became a sort of lottery these days. You never know what you are going to get. That’s not limited only to electricians; all craftsmen today seem to be much worse than 20 or 30 years ago. Usually, you need to hire another craftsman to go after them and fix their mistakes.
In case you are wondering what’s wrong with this picture, all the lights are turned off. And you see one light switch in an opposite position. This must be very annoying. Instead of just swiping your hand over all of the switches to turn them on or off, you actually have to pay attention to what a button you are pressing and what way.
