The people involved are eating comfortably, so it's weird to point it out just because you don't like looking at it.
When people nitpick every little thing just because it bothers them even slightly,
doesn't that increase social stress and suicide rates?
(Is that going too far?)
Using chopsticks isn't a matter of right or wrong like spelling; it's just a difference.
Even during the Joseon Dynasty, when people were even more strict about etiquette, there were no problems with this.
