The king of the coffee industry and the No. 2 quick-service company by U.S. system-wide sales, Starbucks would seem to have all of its ducks in a row when it comes to the back of the house. But the Seattle company apparently has at least one Achilles heel: the drive thru.

According to this year’s data, Starbucks ranked last in drive-thru speed of service and in the bottom half with order accuracy. Further, the company’s customer service scores were average at best—not quite the high-quality hospitality the company touts of its team members.
