Five things you should never do when eating in Japan

Not in my experience. But I use a dishwasher with a drawer for cutlery.

The super nice ones I bought from the Singaporean exhibition, sure.

The standard ones that cost a couple of dollars at most? Nah, not so much. They survive just fine on the ~ 50°C programme, dry out and that’s it. One or two bent too much to be used, the rest works fine.
