(Bloomberg) -- Domino’s Pizza Inc. can’t get enough people to cook and deliver pizzas, hurting sales in the company’s most recent quarter.

“Our U.S. order counts during third quarter were pressured by a very challenging staffing environment,” Treasurer Jessica Parrish said Thursday on a conference call to discuss earnings results. A lack of workers meant some stores were forced to shorten hours, while others had customer-service challenges, she added.

The company posted a 1.9% drop in same-store sales in its home market for the period ended Sept. 12, missing analysts’ estimates for an increase. Despite a hike in wages at Domino’s company-owned stores, Domino’s “continued to experience staffing shortages in certain” locations, Parrish said.
