I've also heard an argument from a coworker that they go out to eat because they "can't make it at home." I find that hard to believe that in this 'information age' where recipes are basically free with a simple internet search that they cannot figure out how to do something, lol.
To be fair, there are a lot of things that are difficult to make at home. I've tried to make spring rolls, and egg drop soup, but they just don't come out like restaurant food. I make my own pizza every week, but you just can't replicate the effect of a real brick oven at 800F with a 400F home oven. I can't make sushi rice with that perfect sticky texture. My bagels never get that smooth shiny crust, and donuts just aren't the same if they aren't deep fat fried.
The difference being, of course, that I've
tried to make those things, and learned that I don't have the tools or techniques to do it well. I've decided it's cheaper to buy the occasional donut, rather than buying and storing a deep fat fryer that would be used 2-3 times a year. I still make pizza and bagels, and just accept that they'll never be as good as commercial - and occasionally, we'll have a craving for really good pizza, and go out for it. But that makes it a special occasion when we do go, just a few times a year.
Now, if they're saying they can't make a burger or Olive Garden pasta, that's just laziness.
