My part-time retirement job is working in a bike store. There's a McDonald's right next door, and I'm usually in there at least once a day when I'm working. The staff is mostly young black high school kids with their first job. I'm a 72-year-old white guy, and when I'm in there they get "Yes Ma'am", "Yes Sir", and "Thank you Ma'am" from me. Kids nowadays showing up for work deserve respect from us older folks. Even if they don't know us, they look at how we interact and learn from it...either for good or bad.
