It is expensive in certain situations. For instance:
if I am eating by myself I can do it for about $5 and eat pretty damn good. Ill eat a few Jr Bacon Cheeseburgers, or Crunch Wrap Supreme and a burrito etc.
If I am taking my kid and wife to eat, I'm spending at least $25. At $25 I can go to a sit-down restaurant and spend about $35 and get some better food.
HOWEVER..... I love me some shitty fast food. I really like White Castle (get a crave case every 3 months or so) and I know for a fact that I have to deal with some asshat behind the counter or someone I cant understand who is running the drivethru window. Maybe every once in a while I will run into a high school student or whatnot.
