Your biggest allowed limits in no particular order are Caesar's Mirage, MGM, Westgate, Wynn 15-25K bets won't get you much attention on a Saturday/Sunday. Once you get to 50K on up, they will get attention. Of course it's common now for them to ask for a players card to get your bet into the system. When it comes time to cash out, they want to see that card again to verify it was you that made the bet. Typically they don't ask for identification but on some occasions depending on the bet size they do. Be friendly, act as if it's not a big deal and avoid idle chit chat. Give them the rotation number, the team, the amount you want to bet and be sure to put your tickets in a safe spot. Also take a picture of your ticket so you have proof they were yours. In case something does happen, you have proof of the tickets plus you can be identified. Low key is an absolute must. Don't act all cool and be a show off, it will get you jacked.
