Silver, All bookies reserve the right to refusal, but don't really want to use it. However, if the customer consistently wins large sums, then the book would be foolish not to at least make some kind of adjustments (lowering limits, taking certain games and teams off the board, etc.) I, personally, remember one customer that I had to finally surrender to, after about 5 years of him winning. I couldn't take it anymore and just told him the truth, "you're too good!" I couldn't beat him and he was eating away at the profits. I wouldn't judge the book as being disreputable if they have done this, as long as it was done in the correct manner. I wish I had bookies wanting to ban me!!! LOL!
