Eating out used to be an occasional event for older generations, often reserved for birthdays or anniversaries. Nowadays, the average American eats out about four times a week and spends nearly $3,000 yearly in take-out food, according to Restaurant.org. The waste created by take-out packaging alone is enough to make you think twice, but when you factor in the money you can save by eating at home or by bringing your own lunch to work or school — in a reusable container, of course — you can see why your grandma eschewed eating out on a regular basis.
