Groupon passed a major milestone late last year, having processed a whopping one million help desk tickets. And that kind of achievement is worthy of nothing less than a giant cake from Sarah’s Pastries and Candies. We descended upon Groupon’s offices last month, cake in hand, to help the Chicago-based company celebrate the big 1-000-000. In fact, the customer support team at the Chicago-based company is so good, it had already processed 1.25 million tickets by the time we made our December trek. Here’s our video documenting the visit.
