Gifting:
Max: 20 gifts in a rolling 24H period, 32767 serving of food or number of parts
In Restaurant Story, you can gift once a day to each neighbor from a select list of gifts, which resets 12AM PST. (Gifting does not deplete your own stock. Nor do you have to have it in your inventory/on your counters.) You can receive 20 gifts in a rolling 24H period. (Requested parts do not count toward this limit.) Generally neighbors prefer original parts (since they are more likely to be reused in new constructables/constructibles), but some neighbors prefer food. (More information on parts in the Constructables/Constructibles section.) What your neighbors prefer depends on the type of neighbor, so ask and let them know your preference.
If you get a new gift not listed here, do not panic. :P. Most likely it is a new part used in a new constructable/constructible in the week's updates.
