Today, May 15 you have two opportunities to get free food
First, Dunkin Donuts is offering a Free 16 oz Iced Coffee today from 10:00 am - 10:00 pm. Unfortunately for me there are no Dunkin Donuts within a 50 mile radius of Los Angeles. But maybe where you live there is one nearby.
Secondly, McDonald's: Free new Southern Style Chicken Biscuit or Sandwich with purchase of med. or lrg. drink. The Biscuit is being offered in the morning and the sandwich is the rest of the day.
The regular McDonald's site is not working for me right now but this silly game site that tells about the free offer is.
