Not exactly a rule but “when you get a paycheck w/ your SSN on it, then you can choose how money is spent.” Cool. Got a job that paid well. Spent my money how I saw fit. She didn’t like but I said “uh ma’am, I’m doing as YOU stated. I got a paycheck w/ my SSN. So if I want McDonald’s tonight, then YES I do have McDonald’s money.” She couldn’t say nothing and no, I didn’t offer her a nugget.
