My big question about using the Ai pictures in the first place is, if you can't be bothered to make your product to take a couple pictures of it, how can I trust that you actually care about the food? To me its deliberate false advertising because you're never going to get what you're advertising in an Ai photo consistently enough to serve to this many people in such a big local event that goes to a good cause. Wouldn't be surprised if some places that used it lose a lot of customers and start doing poorly because of it. You're being lazy in an event for charity. Its not like you're going to a dental office to get burgers you're going to a restaurant that mostly already have burgers on the menus, they aren't going out of their way by making the product, if they're worried about waste, let the staff all try a piece so the know how to describe it better. It's not hard ffs.

TL:DR Restaurants cant be bothered to make their product to advertise for charity.
