What is the ruling on breaking one's fast at "Mawa'id al-Rahman" (charity iftar gatherings) while being able to provide for oneself?

If food tables are designated specifically for the poor and needy, then it is not permissible for others to eat from them, and the condition of the donor must be adhered to. However, if they are general tables for fasting individuals, then everyone is permitted to eat from them, though it is better to leave them for those in need.
