Shortly after turning 18 I was offered a commission job selling Kirby vacuum cleaners with a fairly large guaranteed weekly pay. I product was high quality and the people interviewing were calm, well mannered and assured that we would absolutely not be using any pressure tactics for the sales.
Day 1 we're taught about how to demo the machine and get to tag along for a couple scheduled sales
Day 2 we're taught how to pressure entry into a home for door to door sales demos...
Day 7-ish a friend of the boss joins the group who is super high pressure and boss gets excited to immediately move that direction
After 2 weeks it was clear that this was exactly the opposite of what I'd signed up for (including the lack of guaranteed pay) so I left in search of something better.
My board game prototypes! Can always use more playtesters :)
