This is the same conversation I have at home (with no resolution) when discussing when the ketchup bottle gets thrown out. Should it get thrown out when it gets difficult to get ketchup out, or when the bottle is completely clean?
You cut open the ketchup bottle and scrape out every last bit. (I live by myself)
