To add more anecdata to the pile...
I've been using UberEats for years.
It meant a much larger range of restaurants became available to me - I don't drive, and these restaurants would otherwise not get my business.
Uber Eats has often been very good about giving me refunds for restaurant screwups.
However they sent me an email after a string of restaurants fucking up orders - missing whole meals, or significant parts thereof. At the time, they didn't ask for any kind of supporting evidence, just click through the app and it would instantly refund you.
Then they sent me an email saying that they've detected an "unusual" number of problems, and that they'd like to remind me that fraud is illegal and they may take further action if they detect it. No way to appeal, no way to say "Hey, if you're going to subtly accuse me of being a fraud, at least let me have an opportunity to provide some information".
Uber Eats now (sometimes) asks for some evidence, and it apparently goes off to some human for review (or they just stick a ~30-90 minute delay timer on the processing queue to make it look like a human reviewed it).
Now, most restaurants around me no longer have their own delivery options, and direct you to Uber Eats or a whitelabelled service that just submits the order through Uber Eats or Menulog anyway.
There's a number of fake restaurants now listed on Uber Eats around me, even some chains of fake restaurants.
One of these fake-chains is operating out of low-quality hotel kitchens and is clearly heating up commercial cook-chill/frozen meals.
Another is operating out of a residential apartment building from someone's home (not a commercial kitchen).
Good luck trying to report these to Uber. They don't give a shit.
While I'm dumping these on Uber, they're unfortunately not the worst.
Menulog are IMO worse - they have all the same problems as Uber in terms of fake listings, but also work with restaurants that keep getting bad reviews to wipe out the bad reviews and re-list them as New.
All the business has to do is say they've been sold to new owners, delete the old listing and re-add and hey presto, those 500 1-star reviews saying you've got a shit product are turned into 30 5-star reviews about this amazing "new" restaurant, rinse and repeat every few months when business drops off.
