Matters needing attention in going to KTV
You can't bring your own drinks to KTV. KTV makes a profit from these things.
Pay attention to your money, and be sure to pay attention to your bag outside, because you always forget to take something when you leave, and then new customers come.
Choose a place with good sound quality. To go to karaoke, you'd better find a place with good reviews and good sound quality. Where the sound quality is not good, it is difficult to hear clearly after singing.
Don't quarrel with others in KTV, it's dangerous.
