I worked at McDonald’s in high school in 1983. Neither of those happened where I was, I made $3.35/hr and was given a uniform (polyester, bleh!) that I had to return in good condition when I left.
Of course my experience doesn’t mean it never happened, it just wasn’t overall what you described.
We were still in brown and yellow and there was no cotton. That uniform was hot and scratchy and reeked of fry oil no matter how often you washed it. The women’s uniform was similar to https://www.worthpoint.com/worthopedia/tb221c-1983-mcdonalds-uniforms-4138233506. They’re calling it burgundy but it was brown. Pure 70s brown. Yuk.
