That said, your taking modern society standards and applying to them to someone who is clearly a very traditional old lady. Her idea of discipline is very different from modern worth ethic.

I see her like a Nun in a Catholic School, who disciplined students by smacking their hands with rulers to punish them, or even a parent who spanks their children for being bad (who can get sued for child abuse these days). Heck, the military operated under a similar principle, but once again, modern standards throw a negative light on this.

If my grandmother slapped me for almost injuring a customer at her business while doing something I wasn't supposed to be doing I wouldn't see that as abuse. I'd probably be pissed initially, but I see the logic behind the punishment.

As I have seen mentioned elsewhere, this is very much a cultural difference at play. To someone familiar with traditional Asian values, that scene would be far from extreme.
