Starbucks has reported higher than expected sales in its fiscal second quarter, with global same-store sales rising by 6.2%, higher than the 4% increase Wall Street was expected. The company has been focusing on improving customer service and introducing friendlier service. It has also reinvested savings into its turnaround after closing hundreds of stores in the U.S., Canada, and Europe in the past year and laying off at least 2,000 non-employees.
