    As Americans live longer and the job market stays competitive, fast-food chains are increasingly hiring from senior centers, churches and aging advocacy groups like AARP, Bloomberg reports. And it's not just death rates and economic trends driving the change. Seniors have more polished social skills, but teens are stopped from growing up online with fewer real-world connections.

“I spend a lot of time with young kids. They can he very disrespectful,” 63-year-old Church's Chicken manager Stevenson Williams tells Bloomberg of his teen coworkers. “You have to coach them and tell them this is your job, not the street,” Williams says. Having “soft skills” such as politeness often comes more easily to the seniors, who have had a lifetime of experience in the workforce to learn how to treat customers compared with young people.

Employers thus get a more mature worker at no additional cost but the reasons for seniors outpacing teen hires are many. The US Census Bureau reported this year that, by 2035, there will be more Americans over age 65 than there are children under age 18. Plus, fewer people in their prime (盛年)are working—thanks to the unaffordable childcare that forces many parents to stay at home, according to a study by Princeton University.

The US Bureau of Labor Statistics (BLS) forecasts the number of American workers aged between 65 and 74 will swell 4.5 percent by 2024, while the 16-to-24s will shrink 1.4 percent. By 2024, the BLS projects the labor force will grow to about 164 million people. That number includes about 41 million people aged 55 and older about 13 million of whom are expected to be aged 65 and up.

So don’t be surprised to see even more service with a smile and silver hair in that drive-through lane.
