Cosi (NASDAQ: COSI) restaurants saw sales fall 2.7 percent last quarter, the company's new CEO Stephen Edwards, blames poor customer service as the reason why sales are bad. Revenue for Cosi has gone down every year since 2009. Traffic fell 5% last quarter. Aside from poor customer service Cosi suffers from unhappy workers, Cosi's employees are less satisfied with their company more than McDonalds, KFC, and Subway. I have eating Cosi probably once before, have you guys ever been?
