A burger shop owner has lifted the lid on what he claims is a "huge loophole" in food delivery services that allows rogue drivers to steal customers' meals.

Delivery services such as Uber Eats, Deliveroo and Menulog have taken on a large role in the food industry as diners take advantage of the wide range of home delivery options.

However, restaurateur Shravan Gautam said there was a flaw in the system.

"When the driver comes over here, he shows us the number, we then give them the bag," he told A Current Affair .

"They then have to click and slide on accept, then they get the map to the customer."

However, he claimed some drivers were walking away with the good and instead of accepting the next step, they cancel the order.

"That then reassigns another driver to come over here, but the food is already gone," Mr Gautam said.

On a busy night, Mr Gautam's burger restaurant relies on Uber Eats to deliver most of their orders.

And just one stolen order, he said, was a good night.

"It has been happening a lot more frequently now that Uber drivers seem to be congregating on social media, primarily," he said.

"And they give each other advice on how to con the system, basically."

Customer Mitch Woodward believes his order could potentially have been one of the stolen ones.

The DJ and music producer ordered Uber Eats after working late at home.

"I was watching the app and it said six minutes, and then all of a minute later the app said 'cancelled'," he said.

It was cancelled by the driver, who told the restaurant he had received the wrong food for the order.

"The restaurant pretty much said that they stole the food," he said.

He posted about it on his Facebook page and was inundated with similar stories.

One respondent said the driver had cancelled as they had turned onto the customer's street.

"I got a massive reaction," Mr Woodward said.

"I didn't think it was common, but a lot of people said, 'it's happened to me'.

"They're blatantly stealing food that I paid for."

Mr Woodward did receive a refund from Uber Eats.

Retail expert Dr Garry Mortimer from QUT said when drivers did the wrong thing, it was the restaurants that suffered.

"When the service fails there's certainly a cost to the business, not just in replacing the meal, but also reputational damage," he said.

While restaurants could complain to the delivery service, Dr Mortimer said the only way to guarantee the delivery was carried out correctly, was for owners to employ their own drivers.
