"It's just common sense. A book to book xfer is nothing more than a courtesy to a customer to give credit at shop A for money that Shop A will collect from Shop B."
That's not true Joey. What if I transfer 2 dimes to book A & hit a parley that turns my 2K into 10K. What happens if shop B now goes under & the 2K transfer fell though. Do I lose only my 2K or also my 8K in winnings?
They need a clear policy for this. Hell, offer an insurance policy if need be, but let us know that our funds are safe.
If shop B doesn't pay shop A, then the xfer should be reversed.
Sure, but how long are we talking - day? week? month?
A simple policy would make this info trivial.
"The customer is no worse off if Shop B goes bad, because the customer woundn't have collected from Shop B anyways, and would not have had the use of those funds to post with Shop A in the first place."
Not necessarily true. What if I could have wired or WU'd those 2 dimes over instead of transfered? If the book won't pay those winning then you are fuked (even more than the 2K transfer).
