There is also a rule for Indians to eat. No matter adults or children, they must eat with their right hands, pass food and tableware to others, and even use their right hands. This is because people think that their right hand is clean and their left hand is dirty. This is related to another habit of Indians. Indians, like toilets, do not use toilet paper to wipe them, but use water to flush them. When flushing, they use their left hand instead of their right hand. When eating in restaurants and Indian homes, when the meal is almost finished, the host often brings everyone a small bowl of warm water with a piece of lemon floating on it. This water should never be drunk. It is used for washing hands. After the meal, a plate of green wheat-like spices will be served for everyone to chew to eliminate the peculiar smell in the mouth.
