“People were super upset,” he said, “they were leaving. I’m pretty sure they [Target] lost a lot of money.”

Shoppers were greeted by an employee telling them the cause of the lines was a  widespread computer glitch.

Sunday evening, around 9:30 p.m., Target issued a statement about the snafu.

“Earlier this evening, Target experienced a glitch that impacted the speed of checkout at some of our US stores. Since that time, we’ve been able to restore our check-out process. Once again, we sincerely apologize to anyone inconvenienced by this issue,” the store said in a statement.

Over the holidays, Target had a security breach involving credit card and debit card information for millions of its customers. The store on Sunday wanted to say the problem Sunday night had nothing to do with a security breach.

The computer snafu still left many shoppers annoyed.

“Since it’s a big corporation I would expect for them to do something about it for the customers,” said shopper Marleny Gill.
