I would say I’ve had great experience in hcmc and Hanoi shops and left it unattended, matters most which shop but for the majority no issue at all.

Leaving it in that cliche highland coffee shop location in D1 by that street, yeah, no.

Indonesia too, no issue across Jakarta, Depok, Yogya, Bali, Lombok, etc

I’m surprised at Japan, I would thought it be a zero. No issue at any location at all.
