Decades ago I would prebuy their burittos in evening and throw them in fridge at home, and then take them for breakfast the next day. But their prices have jumped so much, and the quality dropped so much that I now make everything from scratch at home and it is much more satisfying
Because when it is to actually get paid work done, all the bloat adds up and that 3 days upfront could shave weeks/months of your yearly tasks. XKCD has a topic abut how much time you can spend on a problem before effort outweighs productivity gains. If the tasks are daily or hourly you can actually spend a lot of time automating for payback
And note this is one instance of task, imagine a team of people all using your code to do the task, and you get a quicker ROI or you can multiply dev time by people
