You can say it is not a problem or a concern, but it is a fact of what is happening in the highest majority of casinos where the losing customer is sought out by his/her instantly available 'credit line advance'.
"According to the PNP-AKG, Chinese nationals look for gamblers losing big in Manila casinos. Agents approach the target and offer to lend them casino chips in exchange for the individual signing a promissory note. The victim is often required to surrender their passport at this stage.
If the victim wins, the lender requires a 20-30 percent cut of the money. If the victim loses and cannot pay the loan, he is detained in a nearby hotel, where they're often beaten and tortured on camera, images then sent to his family."
"Lim, who was a Philippine Offshore Gaming Operators (POGO) employee, reportedly went to the casino with a friend to gamble last Monday. After losing much money, the Chinese suspects allegedly offered to lend him P500,000 worth of casino chips in exchange for 20 percent of his winnings.
The victim also lost that money and this led to his alleged kidnapping. The suspects reportedly told him to contact his family in Malaysia to pay his ransom."
"Once victims lose anew, they would be abducted and the syndicate will demand their relatives to pay a huge sum of money. The group would even go to the extent of filming the victims while being tortured to force their relatives to pay".
