Just thought of something else. Won't sound scary as much as it's funny really. Although, I was bricking it at the time.
When I was working for Sky as an installer during my uni years. Mainly weekends really. So I got to work bright and early on Saturday, got my job sheets and STB's, loaded up and set off to my first customer. Was working alone that day as my usual partner was doing a sickie, so it was a case of pulling my finger out and working harder.
My first customer wasn't home, but asked if I could install the dish so long and wait for him to let me into the house to wire up the STB. No problem sir. He wanted it against the chimney, where it wouldn't be much of an eyesore as the house was rather nice.
Now, getting onto the roof was risky as it was high. Sky has a 'Special Heights' team that does things us normal guys didn't want to do. Problem is, if I blow it out and give it to the Heights team, it would've impacted my job completion rate and ultimately meant less money. So it was poverty that drove me up the roof

.
It was a 3 tier extension ladder and I still had to reach-jump to grab onto the gutter and pull myself up the roof. Started pulling myself up (not wanting to think about how I was going to get off the darned roof again), when the ladder gave way and tumbled down, leaving me half-hanging from the gutter. Luckily it was a rather sturdy gutter.
I'd say the drop was about 5-6m down, which doesn't sound like much when you're reading it on a screen whilst having your morning coffee, but it's another matter when you're the one staring down at it.
Needless to say, I was bricking it. Because I was weighed down with heavy boots, loaded tool-belt and a satellite dish strapped to my back, I didn't have the strength to pull myself onto the roof from the position I was in. There was also nowhere to shimmy over to, so I started screaming for help. The really high-pitched type screams women tend to generate.
What counted in my favour was that some British Gas workers where digging up the road outside the property and they heard the shouts for help and rushed around the house and stuck the ladder back up. I got down and hugged them all.
Now this story had a happy ending but for many guys in the past working for Sky, well, they weren't always so lucky. I know of at least two contractors that was killed during my time installing and numerous that fell off roofs and broke bones. Be nice to your Sky-Man. It's a crappy job.
