Have you ever asked a neighbor to borrow some kind of food because you ran out and didn't want to go to the store? You know, butter sugar milk that kind of stuff.
Yes, when former housemates lived across the street from us and we were in each other's houses all the time. Otherwise I don't think so.
One time I hosted a clambake and I realized I didn't have enough butter at the last minute. I asked my neighbor and she gave me a pound out of her freezer even though she wasn't invited to the party.
