I ordered Uber Eats once while I was visiting a smallish town on business (~30k people total.) I'd never tried it before but Uber was definitely around as I'd used that service already after having arrived.

I ordered McDonalds of all things, it said I'd have it delivered in 30 minutes (whatever, it was only a 10 minute drive away but I didn't have a car so I couldn't be bothered)

Then the delivery ETA jumped to 40 minutes, then 50 minutes...I sat there for over 90 minutes and it STILL said they were waiting for a driver. I eventually cancelled it, and they still charged me for the food that they claimed was made at the restaurant. I called McDonalds to ask and they said they don't start making the food until they see the driver, so that was BS.

Got the runaround from Uber Eats, they never refunded me (after jacking up the price of the meal too) and I will NEVER use them again, even in a populated area.
