My experience has been bad tasting food or past food poisoning puts people off leftovers...
I love leftovers... especially something like soups or lasagna that are better after a day or two.
But if you can't keep up or tell if something has gone off... then leftovers can be a bad thing if you spend hours chained to the toilet.
My SO was skittish about leftovers, now I'm the standard - if I won't eat it, it gets tossed. (I have had food poisoning so I don't have a weird superpower against off food)
Wouldn't this be a state or city level crime?
