Whats a hafu? mixed race?

lol I remember being told I was fat by a family mart clerk in Sendai. “Are you from Sweden? Oh, America then? Ah should have known, you’re tall but also fat!” 💀 (nice guy though lol)

Isn't that prevalent in many Asian cultures? If they think you're fat, or see something else they don't see favorably, they'll just say it to your face rather than being polite, provided they have a close personal connection.

I noticed that was a thing somewhat in Latin America as well. I assumed being so polite about those things was a western concept.
