Lunch at work

I am really surprised at the cost of food now. I went to work with no lunch yesterday and ended up buying a curried vegetable pie at the local bakery. It was $3.75. A sandwich of salad and cheese would have cost $5. Add to that a drink and I would have been out of pocket $7.50! I work at my voluntary job three days a week. If I bought that lunch every day it would cost me $22.50 a week for
