I remember my brother and I flew to Las Vegas once. And we decided to go to one casino -- to be in Vegas and not to go to a casino is a crime. So we are sitting at the table, the deck is dealt out, and then security comes from nowhere and takes one guy at our table somewhere. It turned out he had marked cards. We were lucky that the guards noticed this at the time, or we would have been stranded. After this incident, I've switched to online casinos and usually play at https://suncity-world.com/ now. You can't be deceived by some guy with a labeled deck in an online casino.
