I have one gripe with them, they do the name for an order thing even though they find your table by color coded bucket. I usually give my kid's name, although Achmed does rattle the clientele and staff. My dad prefers biblical names. Just a time waster to type in names.
Beyond that, yes fast food can be trash. And sometimes that's what we can afford in money or time. And it is possible to stay healthy eating any of them, CFA just makes it easier. It is the only fast food joint left where I get a full meal because waffle fries. The others I have a $5 limit, no fries, no soda. CFA is the only fast food salad edible, the rest use a ton of preservatives and I know because of immediate consequences, the same uncertain feeling I get from Subway veggies. So I usually half a salad, waffle fries and a tea/lemonade, or just unsweet tea.
The drive thru is the best, hit a busy one at lunch and there will be employees with tablets taking orders back in the line. More evidence of what I figure is better managers and better training.
