If you win a lot at the casino, I suggest that you deposit it in a bank or keep it safe. There have been cases where winners were robbed after they left the casino. Disease rate is reported to be quite high. They might know what you are saying.
People mostly like to keep to themselves.
I don't want to live in a landfill. Every time a serious crime happens, the police will set up random roadblocks. You don't want to end up in the police station during your vacation. Lots of time, the prices at those shops are much higher than the usual street price, because the guides might get a commission and percentage off the sale. Play for fun and stop when you should.
