Sharing food
Food sharing is highly valued in Indian culture. It is usual to share your meal with your companion if you are dining with them at an Indian restaurant and both of you order different meals.
However, remember to only share from the serving bowl or dish and not from your plate. Similarly, it is considered impolite to eat off of someone else's plate.
Additionally, it is thought to be extremely unhygienic to dip your used spoon and fork into someone else's food or the primary serving dish.
