That sucks man, I must give you props for playing it cool throughout, like giving them the four options etc.
As you say, the stereotype exists for a reason, and it's a shame. I remember studying economics and you have the notion of adverse selection and "lemons", which the schoolbook example refers to cars in this exact way, sucks.
Hope you get it sorted out brother 🙏🏼
Thanks @williamwest! Yeah online reputation systems like Yelp are becoming more relevant and can help consumers more peacefully resolve issues. Sometimes businesses will change their tune and offer some compromise. Otherwise these reputation systems will at least help others make better decisions.
I like how you brought up the idea of adverse selection in economics... very relevant!
