So, why do Chick-fil-A locations stop delivering so relatively early? It's all about quality control and making sure those delicious chicken sandwiches are made to order. Think about it: if they were delivering till the wee hours, the food quality might suffer, and nobody wants a soggy, lukewarm chicken sandwich!
Customer demand also plays a role - let's face it, most people aren't exactly clamoring for chicken sandwiches at 2 AM (although, we won't judge if you are!). By stopping delivery earlier, Chick-fil-A can focus on serving the majority of their customers during more reasonable hours.
