You could always order the food when you're leaving work, then pick it up on your way home.

Why use Uber eats why not just call the place directly and have them deliver it? Uber eats takes a large chunk of their profits or they over charge you.

When I know I’ll be too exhausted to go out and grab food, I make sure to get it on the way home so there’s no extra drive or leaving the house.

Thanks to COVID and work from home and smartphones and Teams/Zoom, I've gone from an hour commute each way to a constant stream of meetings, texts, emails, IMs, etc. that must be addressed immediately, from 8am to 6pm. I don't think the "back in my day" folks fully understand how much more people are asked to do now. I once obliterated an older colleague when he complained that youngs these days don't put in half the hours he used to. I was like "Um, you used to go to the print office and wait four hours for prints to come out, take them back to the office, proof them, then take the documents to the courthouse and file them in person. In the same time, I'm responding to 100 emails, reviewing 20 documents ON MY PHONE, conducting 3 conference calls, listening to 2 coworkers' breakdowns, and drafting, reviewing, printing, proofing, and submitting the documents you used to sit and wait for." To his credit, he said I was right and I never had a problem with him again.

All of which is a long way of saying that, sometimes, more often than I would like, I can't just "go to the restaurant" because of time or because I'm no longer commuting. For all their problems, the apps mean that I'm eating fewer frozen pizzas and more poke bowls and salads.

If you'd said anything other than pizza I'd give you slack, but you're a damn fool wasting money doordashing/ubering pizza. Order from them directly, it's cheaper and the restaurant gets bigger profits.

ugh, we used to have a REAL country

I just have no idea what life was like in the before time. All these poor souls

Some of us don't have a car and don't want the food to be cold when I get home with it.

So, a few use cases, but it tends to boil down to convenience.

Some people work from home, and don't have time to go get food, nor cook anything significant between meetings, and they're just tired of cold sandwiches and microwave soup.

Spending however long traveling to and from the restaurant isn't always a valuable use of time compared to whatever else you were doing.
If I'm playing games alone or with friends, I'd rather do that than drive around for half an hour.

If you've got kids, loading and unloading them into the car can be a chore.

Or just plain "comfy, don't wanna leave".

Delivery is a convenience that people like. Companies switching to a service with more fees that drive the cost up so high is annoying.

A lot of places have, yeah. They viewed the delivery staff as a fixed cost, and thought the services would mean they only paid a fee per delivery, making it a net savings.
Hard to blame them, since that's what they were told, and it sounds reasonable on the surface.
