Chick Fil A as a chain is the absolute platinum standard when it comes to customer service in the fast food industry, at least for a chain of its size. I have never, ever had bad customer service at a Chick Fil A anywhere in the country.
Same here.
The only problem with them (and Starbucks) is their own success. I see the drive-thru packed at most times and just say “Forget it”. Don’t even feel like fighting the parking lot to walk in.
