thank God for newer books allowing people to cancel bets , use to be unheard of and almost every book if that line moves they do not let you cancel no matter what I bet at Hardrock and a lot of times it does not give me the option to cancel, its not like you can just cancel every bet and I would bet that every book is like that and a lot of times its a lot more than juice I have had it be 15-18 on a 100 dollar bet sometimes some people cannot cancel wagers I am sure ..they keep track of the line moves ..like Memphis today going from -2 to +2 if you had -2 I'll bet you could not cancel it
