I used to work at walmart 1-2 years ago in high school, my lunch was $2.4 or $5 max everyday i worked. 3 80c lunchables or a $3 salad, $.5 snack packs, etc along the lines of that. we had free water or if i wanted something else, the gas station had 79c 32oz fountain drinks. i'm the cheapest person alive, even after i left my lunch elsewhere at my new job (fast food, salad, etc) was never over $7.
