Reminds me of the (possibly apocryyphal) story
...from the early days of microwave ovens. A cafe owner thought that it took too long to open and close the doors of the ovens, so removed them and bodged the safety switches shut. So there were several industrial-power ovens running pretty much continuously, under the counter at approximately gonad-height, irradiating everything that came close.

Dundee, early 80s...
...and it was a chip shop in the Hawkhill. My dad stopped going there when he saw what they'd done to the microwave. A week or two later, the place was closed. The guy that ran it is apparently still around but retired long ago.

It's a Subway now.

(edit: any given story is probably apocryphal, but it seems likely that it happened a lot in the early days of microwave ovens)

If you're in a room with an unshielded microwave oven,
The first thing you notice (after about 15 seconds) is that you don't seem to be able to see anymore. Ever.
