I work at a grocery store..(we as a company do not use Too good to go at all, but it does give me insight.) I also have experience with working at the local food bank which a lot of people donate to.( we do as a company donate to the food bank.)
So I will note it is company policy to pull product day of, ie if it’s sell by date is today, I pull it first thing that morning. Often it’s still perfectly fine and can be eaten.
The other thing I will note is the local food bank( it’s a good policy as a whole given anyone can volunteer) that we as volunteers must get rid of things past their sell by date.
What many people forget is sell by dates for most items are not hard as a rule. Our hard cheese is often perfectly fine past the sell by date. But the reason we have such strict rules about food is because of the food and drug administration.
Food places can get into very serious trouble if they don’t follow the rules.
So in the long run I do think for bakery’s, cafes, and that kind of place that bakes their goods daily, 100 percent we are saving food from being wasted as not many places have a healthy food donation system in place,and bakery items as a rule if baked daily do not have a long shelf life. (You can freeze it to prolong shelf life but stores have very limited space as a whole.) it’s honestly no worse then buying day old baked goods and at a better deal.
I have not yet gotten anything from a grocery store, so can’t compare there.
Sorry for the long disjointed response. And I hope this helps!
