Seems those ads promising help for people suffering from the Big Mac withdrawal symptoms were put on the T by McDonald's local ad agency without the hamburger chain's approval.
In a statement, Arnold President Pam Hamlin says:
Arnold apologizes for its mistake to McDonald's and to anyone who was offended by the ad. McDonald's did not approve the ad, and it's release was our unintended error. We've addressed the issue and have improved our approval process to ensure this does not happen in the future.
McDonald's and Arnold asked the T to pull the ads down (see the other ads).
