they'd never all be closed on Sunday. The day that that happens is the day "McDonalds is the only fast food available on Sundays!"
Chic Fil A makes really good food, they've established they arent open on sundays, I work around that. Judging by the page Saint linked to, I cant be the only one. They aren't losing out on making any money from me, they are just earning it on a different day of the week. Whats so hard to grasp about that?
You're saying for example I wanna eat some chic fil a, and its sunday so I cant so I go get some McDonalds. Chic fil a lost a sale because they werent open. Lets say its saturday, and I dont wanna get McDonalds cause I can get them whenever I want, so I go to chic fil a, cause they'll be closed the next day. Wouldnt that mean they got a sale because they are closed on sunday?
I'm not saying the shift to Mon-Sat is equal to the amount of business they may earn on sunday, but being closed on sunday isnt killing their business.
