I mean, fair if you are already a millionaire, but otherwise it seems good to at least be aware of how powerful saving $20 a day in the long run can be before making this choice
During my holiday this month, I've made it a point to go for a nice lunch every few days. Yes, it costs me money, money that I could save for my future (although I don't know what I would do with the extra money), but it's enjoyable, relaxing and the food is great.
