i'm homeless personally. where once i could survive on $5 a day, i'm always coming up short on the $20 needed nowadays just to eat. so i fast lots, my skating suffers.
Look for little food cabinets outside churches and libraries. Sometimes people put in tuna-cracker kits, a fresh fruit, bottled water, hot cocoa or instant coffee packets. The kits are nice because no can opener, heat, utensil needed. It’s not ideal but not least ideal, either.
