There is no coffee shop anywhere in the world where I would leave my laptop unattended.
Even if things are unlikely to go wrong the level of avoidable risk is simply too high.
A $3000 piece of my personal or worse employer's property and I'm just supposed to "trust"? Not worth it.
you are taking this too literally. try to see it as proxy for questions like 'will i get my wallet back from uber drive' or 'will my purse be snatched by street scooters'
