Chipotle co-CEO: Half of restaurants have poor service

Chipotle co-CEO Steve Ells says that half of the burrito chain's more than 2,100 restaurants have less-than-excellent customer service and that the company is now training employees to clean dirty napkins off tables, make sure the soda fountain is organized and keep the glass on its front doors free of fingerprints.

Ells says the company has been focused on training workers on new food safety protocols after food safety scares last year sickened some customers. Now that the Denver-based company is satisfied with its new protocols, it's turning its attention to better customer service to try and win back customers.

Although there are signs customers are returning to Chipotle, Ells says that he is not "satisfied" with the company's rate of recovery.
