Two men accused of helping Raoul Moat were sent by the gunman to buy supplies after he shot a policeman, a court heard.
Newcastle Crown Court was told Karl Ness, 26, and Qhuram Awan, 23, bought groceries on a supermarket shopping trip.
They claim they were held hostage by Moat and were in fear for their lives.
But prosecutor Robert Smith QC said their willingness to run errands and eat with him showed they were lying.
Moat, 37, was on the run after shooting his ex-partner Samantha Stobbart and killing her partner Chris Brown.
He later shot Pc David Rathband.
The court heard Mr Ness and Mr Awan had been sent by Moat to buy water, cider, burgers, sausages, portable barbecues, buns, ice cream and a bottle of Reggae Reggae sauce.
He also ordered toilet rolls, toothbrushes, fuel, biros, soap, shaving gel, pillows, a duvet and sleeping bags.
Mr Ness told the court he had frozen and was scared after Moat shot Pc Rathband.
But he said he ate "a couple of burgers" cooked where the gunman was hiding.
'You are a liar'
Mr Smith said: "You knew Pc Rathband had been shot that morning.
"How was your appetite? How were you feeling at the time?"
Mr Ness said: "It wasn't the greatest. I was scared."
"But not too scared to eat your meal," Mr Smith said.
"You are a liar, Mr Ness, aren't you?"
Mr Ness replied: "No."
Mr Ness, of Brookside in Dudley, North Tyneside, denies the murder of Mr Brown, attempting to murder Pc Rathband, conspiracy to murder, possession of a firearm with intent to endanger life and robbery.
Qhuram Awan, 23, of Rowley Street in Blyth, Northumberland, denies the attempted murder of Pc Rathband, conspiracy to murder, possession of a firearm with intent to endanger life and robbery.
The trial continues.
