I know a Muslim kid who works at Chick-Fil-A. His mom wears a hijab and is a flight attendant for US Airways.

Chick-Fil-A claims to do more business in 6 days than many do in 7 so I doubt they will expand their hours. As much as I like an on-demand world I notice a start contrast between working hours in the US and Europe and can't say it's always a bad thing to not work 60 hours a week and have everything open 24/7
