Q: What's the most dangerous thing you've seen a repair man do here?
In an old apartment, my A/C ran out of fluid, so the landlord called up a couple of guys to come fix it. They opened the window on my balcony, one guy tied a rope around his waist, and crawled out the window (17th floor), while the other guy held on to the rope. I was pretty sure I was about to witness someone fall to their death.

I can top your scenario by 6 floors. The ropes used are just normal rope tied around the waist, not an actual safety harness. They have been by 3 times to look at that same A/C.
Other than that I see lots of people welding, using jackhammers etc without any safety equipment like goggles or hardhats.
cooter:
Yeah, hard hats are for protecting the noggins of motorcycle riders. Duh.
I had the A/C one on the sixth floor, but just one guy without the ropes. It seems to be quite common.
mArtiAn:
It is common, i've seen it a couple of times. Kind of scary to watch. Still get my phone-camera ready though.
Had a problem in the office with one of the power strips not working. Some dude came in, popped the plastic out cover off, jammed his screwdriver in there and did who knows what with it. All without unplugging the power strip first.
I've been zapped by 110V before...it sucks, actually sorta held me for a moment before I could get free. Can only imagine what kind of pop you'd get from 220V 
Hugh.G.Rection:
I've been hit by 220V a couple of times, it, how do you describe it? Believe it or not the closest I can come is ............ it tickles, but it's quite an intense tickle and it's not on the skin it's inside you.
Cooter:
Just pointing out two things. Many screwdrivers are electrically insulated as long as your hands are touching the handle, not the metal part. So, if you know what you are doing, not really a risk, but I do not advise anyone to try it.
And second, in many foreign countries, electricity runs at 60 cycles per second, and can kill you. In USA, thanks to Benjamin Franklin we do suffer that. But in China, and a few other countries, they run it at 50 cycles per second, and thus it is less lethal. Of course it could still kill you under proper conditions, but chances of electrocution are a lot less than at 60 cycles.
cooter:
Yeah, I'm aware of all that, was just mostly focused on why the dude wouldn't take the simple precaution of unplugging from the outlet. I've always been told 220V is actually safer because it will jolt you away from the source, whereas 110V has a tendency to hold you in place, subjecting you to even more electrical fun (can personally attest to this, yowch). And actually, it's the amps that kill you
