The printed expiration date is not quite an exact time when the food is actually expired. I’m sure most people have the sense to tell if a free gallon of milk is good or not a week after the printed expiration date.
It’s not like food products immediately expire on midnight of a printed date. Free food is free food yo. Some can last way longer than the printed date if stored properly.
And even if a loaf of bread is marginally starting to go stale doesn’t mean much of shit, as long as it ain’t gone outright moldy people will gladly eat it.
And BTW, that tends to be the nature of the food that donation centers give away anyways, food that’s just past the expiration date.
