Food is always up to the Chick-fil-A standard; no complaints there.
I mostly use the drive through once or twice a week and they leave something out at least 25-30% of the time. I must say that I get 3 combo meals and an extra sandwich so I think the extra sandwich messes them up because it's a one-off. The way it prints on the ticket leads me to think there is a procedure flaw. It prints 3 CFA sandwich and then the next prints 1 CFA sandwich so the packer grabs the three and hands it off to the next person. I recommend you check your drive through order. If I go home and find something missing I'll go back about 1 out of 10 times. The other times i just get frustrated with them; but now that I know, it's my own fault that I don't check but hen again I shouldn't have to check right?
