When they only pay $7.50 /hr, its hard to get good people. Some of their employees can't even find the door to get into, and when they do, they can't find the right button on the cash machine to push for the order. But I still like their food when the idiots get the order right.
I noticed on the rankings that Starbucks didn't do very well. Given the frequent waits, etc. (milk needs to be refilled, may need key for bathroom) I kind of agree, but Starbucks rating does cast doubt on rankings as correlating to success.
