In Philippine casinos, there are sometimes people called "casino trustees" who may try to deceive gamblers in various ways or collude with the casino to gain profits. Guarding against these situations requires taking some precautions:

1. Know the rules

First of all, it is very important to understand the rules of casino games. This way you can identify any inappropriate behavior or rule violations.

2. Be wary of unusual behavior

Pay attention to the people around you. If someone shows unusual attention or is overly enthusiastic about your gaming behavior, it may be a warning sign.

3. Protection of personal information

Do not disclose personal information to any strangers, especially financial-related information. This reduces the risk of fraud.

4. Carry cash carefully

Carrying large amounts of cash in a casino increases the risk of theft. Whenever possible, use a credit or debit card for transactions.

5. Choose your gaming table carefully

Choose a reputable casino and avoid engaging in illegal gambling activities to reduce your chances of coming into contact with casino operators.

6. Ask for help

If you suspect someone is committing fraudulent activity at a casino, report it immediately to casino management or security personnel, who will take necessary action to protect the interests of gamblers.

Remember, staying vigilant and exercising caution is the key to protecting against casino scammers.
