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 🙏🏼
