Here, some fans noticed the credit card that he was using to pay for the meal.
It turned out the credit card is the Black from Hyundai Card, which is a card for the super rich.
Available through invitation only, the holder of the card has to be personally approved by the vice president of Hyundai Card and seven members of board of directors.
The holder should have 100 billion won (approximately 83 million dollars) earnings and savings, and has to pay the annual membership fee of 2 million won (approximately 1,700 dollars).
