I agree - the issue lies with the original number but the part that's leaving a bad taste in my mouth is that because that line was adjusted twice, to nowhere near what Tony said the line should've been, signals that this is an internal failure on their end. When that line was first adjusted, was the 5dimes employee just picking a number out of the air or would they have been required to perform their own checks and balances by comparing the line to those hung by Vegas on the same prop? Employees make mistakes so let's assume he/she missed it the first time and didn't bother researching what other places were offering the same prop for. What about the second time the line was adjusted? Again did the employee make a mistake? And if so, should those three mistakes - the initial line and the two adjustments - be absorbed by the customer or by the book itself?
Either it was a bad line all three times and Tony needs to get his company in order or it was never a bad line to begin with and he didn't want to pay out a decent amount on a long-shot bet when it looked like hitting on the final day. Neither of which scenario is a great confidence booster for those who are looking to place bets with them. And regardless of which it was, I don't quite see how the OP should've been penalised his winnings as a result.
