The witness told the Western Cape High Court on Tuesday he had been drinking with a friend before he arrived at the Khayelitsha tavern Sop's Place around 9.30pm on November 13 2010. At the tavern, he drank about 375ml of whisky.
He told the court even though he could drive, he thought it better not to do so.
He said the driving was done by Mziwamadoda Qwabe, who was jailed for 25 years on August 8 after pleading guilty to his part in the murder.
The witness, who cannot be named in terms of a court ruling, was testifying in the trial of Xolile Mngeni, who allegedly pulled the trigger.
Mngeni, who is suffering from a malignant brain tumour, was declared fit to stand trial last week.
The witness testified on Monday that he drove with the two in his car, as well as a male friend and two women, to Gugulethu, the same place the Dewani's shuttle was hijacked.
Anni Dewani was shot in an apparent car hijacking while on honeymoon with her husband Shrien in Cape Town in November 2010.
Mngeni has pleaded not guilty to charges of kidnapping, robbery with aggravating circumstances, murder, and the illegal possession of a firearm and ammunition.
Matthews Dayimani, his lawyer, asked the witness why his testimony mentioned six people in the car, when his statement to police only made mention of five.
"I remember saying we were six," the witness said.
Dayimani asked if his memory was poor because he had been drinking that night. The witness chuckled and said he was adamant there were six people.
The court heard the police never asked the witness for the names of his friend and the two women. – Sapa
