Often times this is the case due to inventory projecting being off and food rotation. As the economy changes, this can affect sales, and change projections. Often this is human error, as it’s a learning experience. The mindset it is better to have excess, than too little, to sell, is what drives this. Just as well, some stores and restaurants are still under the notion they cannot legally donate food, since this type of education isn’t actively pushed or advocated for loudly enough. On top of it, when places do want to donate food, that can also become a complex ordeal due to staff and location constraints, among many other factors.
