Always found that take fascinating -- are you sitting at a sofa or those inflatable chair-like things in the coffee shop? Are you changing your body's position multiple times, like, significantly so?

At least from my side, if I have to work on a laptop outside, I'll just find a good table, plug it in an outlet and, you know, work on it, with almost no changes of body position.

Not to be dismissive but I genuinely don't understand what's the problem with your laptop being plugged in when working from a coffee shop.
