Dealers are often making mistakes.
Boss asked excessive rake.
Normally 1 table are running and its short handed. Food and drinks are awful. Casino has 3 times issue of cheating customers. You can check at internet 'Daegu casino scam'.
Rake is high 10% about $13 USD max plus 2 dollar Jackpot. I highly recommended not to visit there. You better play at Seoul or Incheon Casino to play poker because of better management and better atmosphere.
