Eat your heart out McDonald’s advertisers. Recently, the largest fast food chain in South Africa, Wimpy, set out on a campaign to advertise the fact that they have Braille menus to benefit the visually disabled. How did they spread their message? By spelling messages out on their hamburger buns using sesame seeds. After giving 15 blind people buns with Braille messages like “100% Pure Beef Burger Made For You,” the positive reactions went viral, reaching over 800,000 people. Talk about food for the soul.
