fun fact: supermarkets throw out tons and tons of perfectly healthy food out every day just because their sell by date is up and they need to make room for new stock, if you want to eat for free just raid the bins behind supermarkets and you'll find they're full of unopened unspoiled food thats not even past their actual eat by date
this is a good tip and sometimes there are sleeping hobos there that are so strung out that you can fuck them without waking them
