For example, if you work in a factory, you will likely have lunch, break, and dinner there. At work, there will most likely be a cafeteria nearby where workers can grab food to eat while they wait for a break. In your home, you probably have a microwave, refrigerator, stove, and other appliances to cook food at home.
