Never gonna happen. When I used to work at my university's dinner we used to throw a lot of food away. Some good samaritan from there, a supervisor, decided to hand at some point some to charities and the church.
2 weeks later the university was sued for food poisoning and paid more than 250.000 in damages. America literally commits suicide with this kind of issues since the legal system is so messed up.
True :(
We would have to fix a lot before we could do something like that.
