Sharp-eyed and highly caffeinated regulars might have noticed the brand-new employee at the Mercer Island Drive Thru Starbucks in November. The newbie, wearing the standard-issue green apron, was receiving a crash course in just about every function at the 1,800-square-foot store. He took a turn as a barista, manned the drive-thru, handed out samples to customers, took out the trash, and assisted a patron who was trying to connect to the Wi-Fi network. He tinkered with the store's point-of-sale (POS) system. He even did some scheduling.
