Well, if it works for you... where I live you’d need to have a Conceal & Carry license to go where the food terminal is, particularly between the time you are suggesting 10 p.m. and 3 a.m. What do YOU do for a living? I and most of my friends work and get up at 5-6 a.m. for work, etc. so being out at 11 p.m. foraging for food isn’t going to be very good for the sleep cycle.
No thanks. While it might be a great way to save money, my life is more valuable to me.
Where I came from, they called that "coon hunting"!
