More frustration for Target customers

Neither Target (TGT) nor its customers have had an easy time these past six months.

With the retailer still recovering its footing after a massive security breach late last year, it was hit by another technology-related glitch over the weekend. An unspecified problem "impacted the speed of checkout at some of our U.S. stores," the company told CBS MoneyWatch in an emailed statement.

The glitch is unrelated to its earlier security problem, Target added.

While the retailer said it's since been able to restore its check-out process, the latest misstep is a setback as it tries to regain customers' trust following the security breach, which affected as many as 110 million Target customers.

The fallout has impacted Target's brand reputation, led to millions in expenses for the retailer, and caused an executive shakeout, with its chief executive stepping down last month.

With the check-out glitch, customers posted photos of long lines on Twitter, as well as frustrated messages.

"Target check out lines just shut down," one Twitter user wrote. "Super thrilling experience right now."

Target apologized for the glitch. "Once again, we sincerely apologize to anyone inconvenienced by this issue," the company said in its statement.

Customers in at least five different states complained about the problem, CNBC notes, although the company didn't immediately specify how many states or regions were impacted.
