Casino markers are similar to most other types of loans. However, there's one major caveat: if you don't repay the money you owe a casino, you could end up in jail, on probation, and with a lifelong criminal record.
Casinos are fun entertainment venues that people visit to have a good time, but just like any other venue, casinos have rules that all visitors must follow. Anyone who breaks these rules may get kicked out or may even find themselves added to the casino's blacklist and permanently banned.
