Back in the day I used to buy my lunch from one of the surrounding sub shops. That worked pretty well--it was \$5.00 a day or so and it guaranteed me a meal that sufficed to get me through the day.
Recently, I started to think about the economics involved:
5 dollars a day * 5 days a week * 50 weeks a year (roughly factors in holidays and vacations) ----- 1,250
I figure that I can make my own sandwiches and cut that cost at least in half. Thus I started to bring my own lunch most of the time.
The other day I bought Pepperidge Farms Sweet Buttermilk bread since it looked pretty substantial. However, I discovered a sandwich made using this bread is not unlike eating two spoonfuls of peanut butter and two spoonfuls of jelly. A sandwich is not a sandwich when the bread part of the sandwich is rather insubstantial.
