Brands (NYSE: YUM) , Texas Roadhouse (NASDAQ: TXRH) , and Starbucks (NASDAQ: SBUX) top that list. Labor costs, the largest expense item on Texas Roadhouse's income statement, were the main culprit, growing 17% from a combination of inflation and increased hours worked. Finally, Starbucks is facing stepped-up competition this month from Dunkin' , which is rolling out espresso machines to its entire franchise base in a bid to push its offering beyond the drip coffee it's already known for.
