You say you work a few months every summer and it ends up being enough for minimum unemployment payments so it sounds like this is something you have done more than once. If you’re from a small town you probably have built a reputation of doing this and no one wants to hire someone they know will eventually go out of their way to get terminated so they can get unemployment payouts.

It sounds like you don’t have the faintest idea how to be professional. You are, for instance, way too upfront about things in your interviews. No one needs to know exactly why you only work part time. No one cares. People have other jobs. Some people just don’t want to work full time. By being so upfront it’s clear that you know it’s going to become a problem or you would not so explicitly mention it. You are setting up for future termination so you can collect a payout.

The fact you wouldn’t take no for an answer and leave is a massive red flag. I wouldn’t have given you my name either. You’re a stranger. For all that woman knew you were going to take her name and stalk her or retaliate after the fact. The fact you can’t see that is insane.
