In the Philippines, senior citizens are entitled to a 20% discount on food and beverages, including at fast food outlets. If a senior citizen is dining with a companion, the discount typically applies only to the senior's order, not to the companion's meal. However, some establishments may have specific policies, so it's best to check with the fast food outlet beforehand. Always present the senior citizen ID to avail of the discount and inquire about any additional terms they might have. For the most accurate information, it’s advisable to review the official guidelines or ask the restaurant directly.
