Okay.... THIS is just ridiculous!
Mc Donald's provides a valuable service to the impecunious mother!
I can feed my whole family at Mickey D's for $4.00 (4 double cheeseburgers and 4 waters). It's not super-healthy, of course, but as a once-in-a-while "eating out" treat, it works.
Try to find a sit-down restaurant where you can eat for a buck....
If the organic-vegan fancy sit down restaurant opens in the ghetto, no one's going to eat there. Why? Because the nutrition/$ ratio is just no good!
