I think lot of places offer discount. I can go to El Pollo Loco and get a great chicken salad tostado for 4.95 out the door, senior discount included. They have a lot pot healthy items and the taste is good.
Either McD’s former customers are going to those places, or like me they are simply bringing their own lunch to work (to cope with the “new normal” economy). My family used to order pizza every couple of weeks (on payday), and would stop for fast food if we were travling on a day trip; those days are over (and probably won’t be back here in the northeast). Income now is reserved for groceries, gasoline, and property taxes.
