Hmmmm. The research being done by CarryOn PR and Label-Conscious Branding for my new mobile ap "Tseen" is telling me that the Top 10 Corporate Food Chains for teens ages 13-18 include Subway, McDonald's, Chipotle, Five Guys, Cheesecake Factory, Taco Bell, Olive Garden, Pizza Hut, Sonic and Starbucks. And....a third of McDonald's employees (including franchises) are teens -- almost 570,000 -- and that number looks to be increasing up to 5% annually. Good or bad, these chains influence teens pretty significantly.
