Not quite that upscale, but for another personal anecdote:
When I was 19, I lived in a rotting slum in one of the dodgiest bits of Sydney. There were half a dozen of us living there; we were all heavy methamphetamine users, and half of the household were into heroin.
Amongst the many other failings of the house, the front door was impossible to properly secure. One day, as the household was gathered in the lounge room eating cheese and crackers, a random dude kicked his way through the front door, grabbed the cheese knife off the table and held it to the throat of one of the girls while he demanded we give him some heroin.
Being the house that it was, one of the girls had some stashed upstairs. However, being the girls that they were, they weren’t going to hand over their best drugs to some random arsehole for nothing.
So, instead, they talked to him until he calmed down, then gave him a couple of cones to smoke and sent him on his way. No blood spilt on any side.
