The chain gave away 4 million meals before it began refusing coupon-holders, some of whom protested in the blogosphere and staged sit-ins in stores. At least two have sued. KFC, which is trying to shake its fast food image and has even started calling itself KGC -- as in Kentucky Grilled Chicken -- in some commercials, has issued rain checks.
"We apologize to any customers who were inconvenienced and we remain committed to providing a free Kentucky Grilled Chicken meal plus a medium soft drink to those who submitted valid coupons," said KFC spokesman Rick Maynard.
