It is reasonable to asume it is not safe to gamble at brink and mortar casinos if one lives in developing countries, to be honest. After all, we criminals know that casinos are a place where they can find easy victims for them to mug or even kidnap to get money, people who carry a significant amount of cash with them and are intoxicated, making then easy prey for them.
It's a hazardous movement, you never know what will happen. It's complicated to carry a large amount of gambling money. Robbers always target people who have a lot of money and take everything they can get their hands on.
Maybe someone that hasn't had trust issues will go about carrying large sum of money to a casino playground, in as much as these criminals are aware of the the type of person that gambler is, they are liable to attack him someday or maybe kill him if he tries to protect his funds by fighting with this criminal.
