Katamon rules.

…No, Katamon doesn’t rule, but look, it has rules! Or “etiquette”, rather.

There’s no direct link; Go here, then peek down to the third to last link on the left: “Katamon etiquette.” Click.
Read it down. Laugh it up.

[Note: Maybe I shouldn’t be so mean. The fact is that a lot of these things are true ‘rules’ of living in this area, or cultural behaviors, rather. And people need to know them so they don’t feel stupid or out of place. We learn them pretty fast though. The dating tips prove how much I wouldn’t make it here alone. Anyways, it is nice that someone took the time to post ‘cultural tips’ online for newcomers.]
