The ad, promoting the fast-food chain's Zinger Crunch salad, featured call center workers singing unintelligibly while eating the salad.

The majority of complaints had to do with manners, and the notion that talking or singing with one's mouth full sets a bad example for children. Other complainers said the ad made fun of people with speech impediments, and a few said it cast call center workers in a bad light. The ASA did not censure KFC, as it said no rules had been broken.
