A couple of years ago, I was working in a computer shop as a "technician", I was 15, first job I ever had.
One day an elderly lady came into the shop, probably 50'ish, she and her whole family "suffered" from electromagnetic radiation, and the mother had the worst suffering. She complained about her TV box that just had died.

I accept the tuner and see it's wrapped with 10 layers of aluminium foil, with a tiny hole for the IR receiver.

The whole box smells like burnt electronics, and the foil gets darker for each layer I unwrap. I try explain to her that the box gets warm and overheated by wrapping it like this, and she's lucky that it didn't catch fire.

I further explain to her that she will not get a new box, because the warranty does not cover _this_. The mother tells me she has to wrap it like this, because she gets headaches when she's watching the news.

She then proceeds to go into a rage mode and gets her whole family into the shop, where all of them starts yelling at me, the younger kids start throwing stuff down from the shelves and touching the TVs with sticky fingers (literally, sticky, like yuck!).

Unsure what to do, boss is in a meeting, and my colleague is busy in the back.

So I calmly tell them that in this building there's 4 wireless networks, 3 wireless phones, high voltage cables run in the wall behind me, there's factory tracks 20 meters behind the building, next door business is an electrician, you're standing in front of wall with 30-40 TVs, 5 HDMI splitters, 3 TV boxes and a Blu-ray player. And they've all been standing in front of them for the last 10 minutes.

They all suddenly feel really sick and run out of the store, never to be seen again. From that day, I decided I'll never work in a shop again, and pursued my dreams to become a developer.

TL;DR: Family is "sensitive" to electromagnetic radiation, almost put burnt down their house because of stupidity, yelled at me. I decided to pursue my dream as a developer.
