I 100% agree with you that nobody should be telling him how to be poor. He is an adult and whatever works for him works for him. We don't know where he lives or what his options are.

That being said in my younger days when I never had more than 50 to $100 in my bank account, I did pretty much only eat cereal, ramen, peanut butter and jelly sandwiches, soups, ham sandwiches.

To me ordering takeout on a regular basis sounds more gross than any of the above options.

Just out of curiosity, how much do you think you are spending on food delivery each month?
