The only reason the lines backup now is because they don't use the normal drive thru system anymore. They try to be innovative and have people standing outside with iPads to take your order. Then you sit and wait for them to cook it all because they took too many orders at one time.also they usually have multiple lines all merge into one window. It's madness over at the chic fil a drive thru!
Having worked at a Wendy's, McDonald's, and a Chick-fil-A... The Chick-fil-A system is superior. At least from an employee standpoint. The amount of volume that we could move through the drive thru with the two lane system and people taking orders in person was kind of insane.
It is exactly like you said, but the line moves! It's nothing like other fast food restaurants. Yes chick looks like madness, but it's a controlled madness. It reminds me of Costco. If you been there during peak hours, it's a total madhouse. But, a controlled madhouse.
Idk before our Chick-Fil-A added the second line and started with the iPads, the line extended out onto the four lane road leading into the parking lot and back a block or two.
Same with the restaurant I work at, the parking lot is woefully too small for the volume of traffic we get, and the line regularly spills onto one of the busiest roads in town and holds up traffic badly. We're the third busiest restaurant of its brand in Canada.
