My thoughts exactly. When you have a business you need to factor in the cost of employee mistakes, etc into your operating costs. It is an internal issue between employer and the employee(s) and the quality of their work. If their employees arent doing their job then thats their problem, not mine. Any store will honor a price that was a mistake until it realized, fix it, and move on from there. I really hate this issue of bad lines. It's not my responsibility to make sure the book is doing their job. With that said, I still WILL NEVER knowingly bet a bad line, because as many posters in this thread have already correctly stated, it's a lose/draw proposition. You wont cash.
But for those of you who strongly take the book's side on this issue, let me ask you this.
Did you ever think that books do this shit on purpose? Ever think they're the ones taking a free shot at the player who's dumb enough to wager on the bad line? Because if the player wins, bet is voided. Player loses on the bad line bet its a loss. So its actually win/draw for the book. They mix in one or two of these lines every other day or so, this way its not blatantly obvious what their doing since a book like 5d offers tons of sides each day and nobody notices shit. And since one player doesnt know another in the offshore world, they cant compare notes and see that Player A's bet was voided and Player B's bet was graded a loss for the same event.
