The difference fram racing to rally is distance. It it easy to give racing marshalls free food and drink, that is harder for rally.

I have heard that in Norway some rallies have used sponsors to make a goodybag, they drive out with the security check team before the rally starts. Contain food, drink, some nuts and chocolate, and some ok giveaways from sponsors. Some have also added a giftcard. That is one way of doing it.

Does any country have an online list where people can register, for rally organizers to go in and check availability, well in advance?
