TEXAS — Texas' favorite grocery chain H-E-B was quick to address shoppers on Twitter Wednesday afternoon as they took to social media to complain of problems at the checkout line.

"Some H-E-B stores experienced an interruption in service at checkout, but the impacted stores will be back online in a few minutes," said Leslie Sweet with HEB. "All stores are open for business as we expect this interruption to be restored quickly."

Shortly after 3:30 p.m. H-E-B told KVUE that all of its stores were operating back to normal.

H-E-B also responded to a few people on Twitter, stating staff members were working to resolve the issue, which was caused due to a system update.

H-E-B did not specify how many stores were affected during the outage.
