To be barred from betting at a sportsbook
is to be told that you're not allowed to place any more bets
there. Some books will bar a player for consistently winning significant amounts; others pride themselves on being willing to take all action
Example: Jackson was barred from the sportsbook after he took out his frustrations from a losing bet and smashed his beer bottle against the wall.
