Of course they all dip into the post up money. If a book owes out to players 150 dimes, and there are 600 dimes in post up money, why would that book run to their bank and take money out of their bankroll, when all they have to do is click a few buttons on NETeller, and just like that, their 600 dimes in post up, is now 450 dimes. BIG DEAL!! I know the mentality of bookies, they will dip into post up, then say, ahh, we'll make it back, we can't lose. I'll dip into the post up for now to get me out of a hole, and hopefully, we will win it back and won't have to worry about it later on. Why go through all that trouble now, when it's that easy to just dip into the post up money. Much less work involved too.
