Yes, different cultures have different ways of figuring out meal quantities. In some cultures, it is customary to prepare an abundant quantity of food so that there is plenty for everyone. This is often done to demonstrate hospitality and generosity. In other cultures, meal sizes are typically small and individuals are expected to take only what they need. 

In Japan, for example, it is considered polite to take only a small portion of food and to leave some on the plate. This practice is known as mottainai, and it is a way to show respect for the food that has been prepared. In China, sharing food is an important part of the dining experience. People often share dishes, which encourages them to take less food and to conserve resources. 

In the Middle East, hospitality is very important and food is typically served in large quantities. Guests are expected to eat as much as they can, as a sign of appreciation for the host's generosity. In the United States, it is usually considered appropriate to serve enough food to satisfy the appetites of all guests. 

In general, it is important to remember that culture and customs vary from place to place, so it is essential to research the culture of the people you are serving to ensure that you provide enough food for everyone to be satisfied.
