Had some pretty bad service at a local fast food place where I noticed that the place was almost entirely run by teenagers. I was getting angry and complaining to my boyfriend when I realized that the fast food industry generates billions of dollars in profit and intentionally pays low wages that most adults with high financial aspirations and responsibilities (ie, home ownership, families, etc) could never live on. Which makes teens and young adults their prime demographic for employees.
I'm so glad I found this thread and see things this way now.
