I've done a fair amount of customer service jobs so heard my fair share of complaints. Like once, an alcoholic threatened to bottle me if I didn't sell him vodka. He wasn't evil or even a bad guy. Just a good guy having a bad day.
There was this one guy however - another completely different job - who complained the wifi wasn't working. Instantly gave me the heeby jeebys. Shouting, threatening without actually threatening violence, dead eyed, just gave off really psychotic vibes. He was a bully but there was something else going on there.
Turns out he was a successful local businessman who was known for his psychotic behaviour and being someone you don't cross. He'd obviously gotten to where he was because everyone was terrified of him.
Edit: another guy I encountered while he was drunk - made really creepy jokes about sexual things, one being 'incest is the game the whole family can play'. I'm 100% sure they weren't jokes - he meant what he was saying.
Scotland. Five bins outside my house - biodegradable, plastic, paper/card, glass and landfill. Everything collected twice a month except landfill (every 3 weeks). Drop-off centre for anything bulky, charity donations etc. All handled by local gov and paid for by local taxes. Works pretty well tbh. Socialism ftw 💪
Some people get their knickers in a twist about all the bins or the infrequency of collections but neither bothers me.
