A Whataburger employee has been arrested after he was allegedly caught with a notebook he used to keep names and credit card details of drive-thru customers.

Dyitez Williams, 22, was arrested by police in Dallas, Texas, after allegedly spending $800 on men's underwear and pajamas.

One customer, known only as Andrew, said that after visiting the drive thru on North Stemmons Freeway with his wife on January 6, they noticed abnormal spending on their credit card statement.

He told WFAA that several hundred dollars had gone out of their account, $800 of which was spent on men's underwear and pajamas at Macy's.

After reporting the fraud to police he called up the store and asked for the name of the person who had made the purchases.

Andrew then looked him up on Facebook and recognized him from the drive-thru before police confirmed he worked there.

He said: 'You can't miss that hair. You can't miss it.'

Williams was arrested on the night of Friday January 10. When police found him he was wearing a rucksack with a red notebook inside that had various names written down.

Andrew said: 'Card information, addresses, phone numbers, and we were one of them.'

Williams has now been charged with fraud and police are working to find all the names in his notebook.

Andrew's money was refunded.

He said: 'It really aggravates me that people think they can get away with it all the time…not this time.'

A Whataburger spokesman said: 'Customer privacy is very important to us. We are actively cooperating with the investigation and ask that any additional questions be referred to the Dallas Police Department.'
