I remember when I was in Jeju wanting to buy a drink at the mini market. It was just the two of us and we wanted to buy 1 bottle of large mineral water. But the seller spoke Korean and offered 2 large bottles of different brands. I thought it was buy one get one free. Because the seller couldn't speak English. Then, spontaneously, the effect of frequently watching Korean dramas. "Hana Free Hana" so it was time short $HANA $
