4. Gambling on Credit
It takes a high level of trust for a casino to allow you to gamble on credit. As a high roller, this is one of the perks to enjoy, and you don't have to carry a ton of cash with you to be allowed to play. You can quickly walk into a casino, and after the session, collect your winnings much later or settle any debt later in case they lose. No average player would be allowed at a table without having cash upfront.
