Final answer:
No, Taco Bell was not the first to introduce free drink refills; this practice likely started with local, independent restaurants and became widespread across the US without a specific originator.
Step-by-step explanation:
False, Taco Bell was not the first to introduce free drink refills. The concept of free refills in restaurants is believed to have originated in the United States, but there is no conclusive evidence pointing to a specific restaurant chain such as Taco Bell as the first. It is more likely that local, independently owned restaurants offered this perk before it was adopted by larger chains. The practice became widespread across various types of eateries in the US including fast food chains, diners, and casual dining restaurants. Today, free refills of soft drinks are a common practice in many restaurants across the nation.
