If they offer you a bonus to cancel a pending payout is pretty much a flashing neon sign yelling run not walk out of there, IMO.
Other than naming actual books
Can you guys help with some solid signs please.

PS I find it strange that a Book allows you to bet a grand on the game, but forces you to take two payouts/2 weeks to collect if you win (ie VegasVic)--and at high P2P charges. Defeats the purpose of their reduced juice odds.
