Arby's, 1964
The name is a play on the letters 'R' and 'B.' And despite some claims that it’s an ode to their classic sandwich, it doesn’t stand for “roast beef.” Rather, RB stands for Raffel Brothers, a nod to founders Leroy and Forrest Raffel, who opened the first Arby’s in Boardman, Ohio, on July 23, 1964. Arby’s was the first fast-food chain to ban smoking in all its restaurants.
That's correct.
It also became a soft drink by accident. One day someone walked into Jacobs Pharmacy with a headache and needed a bottle. It was originally intended to be mixed with water before drinking. He didn't want to wait to get home and asked for it to be mixed at the soda fountain there in the drugstore. The tap was down at the other end of the counter, so the man behind the counter just mixed it with soda water. The result is what we know today.
