This is common because there's probably some other, major time savings things that your wife is able to spend money on that lets her have a reliable stock of food that she can plan and prepare for her lunch.
Beyond time, I will go out of my way to make larger portions for leftovers because I know what's in the food I make, and I try to make healthy food. Even "healthy" options from places that deliver aren't always that healthy. There's an element of knowledge about what I eat that is equal to cost savings in my mind.
Yes but you have to spend time making it beforehand dummy. (Not saying it's not fiscally irresponsible to get delivery for lunch every day, but you're obviously missing the point of the convenience)
I understand the convenience, and I'm explaining that if you are smart enough to plan ahead once in a while, convenience is overblown.
It is few taps in an app and going out for it when it arrives. Literally. And while you are at work anyway. Cooking, shopping and packing take more time - and at the time when you could have been doing something more pleasurable (like chilling with netflix).
For me cooking is meditative enough that it can be included in "chilling with netflix". :D
