I've never used the PWer as a weapon, but...
I know a guy who had to.
He was washing the outside of a methadone clinic (a place where herion addicts get methadone to start weaning themselves) that had just closed its doors. The state support was withdrawn, for various reasons, and the building owner needed to clean the place quickly, to be able to rent it out. He wanted to distance his building from its past.
Well, the problem in the area was never the addicts getting treatment, it was the vultures that were always hovering to take advantage of them. Dealers, pimps, short-con guys, strong-arm robbers, and small-time shylocks; you know, the local pillars of society.
Anyway, these enterprising folks were suddenly bereft of their best revenue stream, and in the absence of low-hanging fruit, were looking for new opportunities.
My friend was washing the filthy entrance walkway, when some shabby-looking young citizen in ill-fitting sports clothing walks up and says something.
"What?" queries my pal.
Same mumbled response. No eye contact, just some indecipherable gestures.
My pal closes his ball-valve, and switches to a wand while saying, "What do you want?"
Our fine citizen says, louder this time, "Break yo'self!" Local patois for, "I'm a little short of cash right now, and I feel as if you should contribute some funds toward my recovery. I am willing to employ force to achieve the goal of separating you from your money and valuables in order so sustain my current lifestyle."
My pal gave him something instead of money: a drenching of water, heated to around 180*, at a rate appoaching 8GPM, from a smashed hosebarb as a shootertip.
Apparently the youth in question had planned to purchase a warm shower with whatever money he acquired that day, because, having received a
free shower, he departed the area, and was never seen on that job again. Or perhaps he had a religious conversion due to his baptism, as he did seem to be exclaiming some religious language, of a sort, as he hurredly departed, no doubt bent on witnessing to the local masses. I couldn't say for sure, as I wasn't present myself, this being a friend's experience, not my own. I will only say for sure that we all know what cleanliness is next to.
I'm sure it felt good to give back to the community.
