I'm not a full-time remote worker, but as mentioned above, I do work out of cafe environments quite often. Why? Well, in my case, I'm single, I live alone, and if the only place I'm ever at - besides my day-job office -
is my apartment, I'd get really bored and go stir-crazy. For me, the cafe is a "3rd place". That is helped by the fact that I drink copious amounts of coffee.
Also, sometimes (as somebody else in one of these threads mentioned) there's something satisfying about being around other people, but not being required to interact with them. And there's something about the hustle-and-bustle / hum of activity in a cafe that is comforting. See, for example, how some people working in an office will put on a "coffee shop noises" audio track while working, to attempt to partially simulate that environment.
$25 a week spent on breakfast and coffee plus a new environment isn’t really going to ding my budget, maybe that is different for other people depending on their field.
