Not a sportsbook but the tables at the Gold Coast. A buddy and I were making good money at 3 Card Poker. When I went back the next day the pit boss said "You're 86'd."
Funny thing was that my buddy and I went across town to the Sun Coast casino and played the table games there. So this urban legend about getting booted from a casino and having your name put on a list to be barred from all casinos in Vegas is BS. Hell, even the Coast properties didn't contact their other casinos.
I love to go to the Chinese restaurant (Ping Pang Pong) there at the Gold Coast Casino and still do when I'm in town.
