"As both a customer and food operational partner of this fascist company I have seen first-hand just how bad [an] experience it is for both parties involved," he wrote in a scathing Facebook post.
Speaking to the ABC earlier this week, UberEats general manger for Australia and New Zealand, Jodie Auster, admitted mistakes were made. "When we're delivering at this scale, some orders don't get there in under 30 minutes, some orders don't get there in the way that they have been originally intended," she said.
According to its contract, a copy of which was published by the ABC on Monday, UberEats requires restaurants to "acknowledge and agree that Uber is a technology services provider" and that it does not "provide any delivery or logistics services".
Rather, the app allows restaurants to "connect with independent providers of delivery services" who "shall operate under cover of your retail license privileges and control, as your agent, and not employee".
"For the sake of clarity ... you, through the services provided by the Delivery Partners, are responsible for the delivery of meals and you maintain possession, control and care of the meals at all times," the contracts read.
"You maintain title to all meal inventory until each meal is delivered to your customer. You are responsible for the costs of all substandard meals. You are responsible for costs related to reimbursement to your customers in the event any such customers request a refund for unsatisfactory meals."
According to the Australian Competition and Consumer Commission, those terms may be unfair.
"The ACCC continues to be concerned that third-party delivery services can place unreasonable conditions on small business," a spokeswoman said in a statement.
"The ACCC will examine Uber's contracts with business and consumers for any potential breaches of the Australian Consumer Law. The ACCC will also consider any representations made by Uber to determine whether there is any misleading or deceptive conduct.
"The ACCC would have concerns where businesses impose terms and conditions that are one-sided. Certain terms and conditions may be legally unfair within the definition of the Unfair Contract Term prohibitions under Australian Consumer Law.
"These agreements can also impact on effective competition in the food delivery market."
An UberEats spokeswoman said: "We are actively co-operating and working with the ACCC to assist their investigation. Complying with Australian law is important to us and we will work with the ACCC to ensure this."
