Before given guidance on expensing when I was a younger and newly hired, they said spend like it is your money, be reasonable. I was a poor kid. I expensed one subway sandwich and stretched it three meals and felt guilty expensing a snack later in the evening. When they later clarified and said I had $70/day, I realized they have different life experiences for what a person spends. I also ate better than I ever had in my life.
