Withdrawal options and promo terms
I strongly concur with Adam Whit's comments.
Operators should be required to make withdrawal transfers immediately on-demand, such that they are credited to a customer's bank account instantly.
Promo terms are often misleading, such as "free plays" which are designed so that they can never be cashed out. Operators should be required to state them clearly and unequivocally, giving concrete examples of how they work.
