From 18-22, I spent four years working at McDonald's. I worked a mix of part- and full-time over these years, always failing to find a "better" job. I never advanced up the rungs, never was a manager, never achieved anything of significance in my time there.
Basically, I was the absolute stereotype of a deadbeat McDonald's worker. Lazy, stupid, with no initiative.
Over the years, I saw this stereotype play out in a number of ways. The faces of my parents friends falling when I told them what I did. The snide remarks, "Do you still work at McDonald's?" or "I could never work at a place like that." Encouragement from my friends, "Just don't show up to work today!" (Because it's not a real job.)
