Yes, it used to be that inexperienced teens could get their first jobs at fast-food restaurants. My first job at 16 was at a KFC franchise and all the fast-food places in the DC suburban town where I went to high school were staffed with fresh-faced teenagers. It was a good way to learn work ethics and get some experience so you could go on to a better paying part-time job.
Now it seems that the fast-food places are all staffed by immigrants. They get the orders wrong and half the time you can't understand what they're saying.
In the "olden days" we fast-food employees had to be quick, friendly and accurate. We caught heck if we weren't. That doesn't seem to be a requirement anymore either.
I have to say tho -- I prefer my local chik fil a -- I never have a problem with anyone understanding my order there.
