Best of three?
B : People want to be left alone.
A : You don't think I can do this job.
B : No, I don't.
A : I bet you I can recomend and sell a book to this bloke.
B : Tenner.
A : You're on.
A : Hello...?
C(ustomer) : Will you leave me alone?! I'm sick and tired of being hounded by salesmen!!!! I'm browsing, all right?!! Browsing!!!! At the end of it I might buy something, I might not!!!!!
After C's finished yelling, A comes to B and says "Best of three?". What does this mean? Gee, why didn't I think of 삼세판?
