I hate bookies that don't accept your live bet because the odds lowered by 0.05% but they accept your bet when the odds rise by 25%.
I'm talking about Pinnacle now. I took Kovalik to win first set at 2.07 but they didn't accept because it dropped to 2.0. Then I bet again at 1.71 but the odds moved to 2.07 again during confirmation, of course they accepted the bet at lower odds. Fair bookies would have accepted the bet at the higher price. As if the deck wasn't stacked enough already against us.
