Taco John’s relinquished its legal claim to the phrase following a challenge brought by Taco Bell. The smaller brand said it would abandon the service mark it holds through the U.S. Patent and Trademark Office, citing the cost of legal fees to fight the megachain. The phrase was born in 1979, when Taco John’s franchisee Dave Olsen, in St. Paul, Minn., came up with a way to boost business on a usually slow weekday. #shorts #tacotuesday #tacojohns #tacobell
