I’m not asking about the worst job. I’m asking about the grimmest one. For me it was when in my teenage years I was making candles you would put on a grave. Most of the time is was just filling the form, burn the right shape and passing it forward. But sometimes I had to fill in for a person who was selling these things, and that is where it gets grim. It was decades ago but I still remember one lady who asked what would be the best candle to memorialize her late husband. And she gave me the whole life story of her and her husband. I shit you not, it was the most touching love story I have ever heard. I quit the next day.
I mean, I worked for an advertising company (they didn’t advertise they were an advertising company until I had already started the job) until they laid me off and at times had tried to figure out ways how to bypass ad blockers for like making social icons not get blocked, and learned a little bit about how ad blockers worked.
Maybe this isn’t quite what you had intended but advertising is really aggressive and gross imo.
