Reasonable cause to believe a check is uncollectible requires the existence of facts that would cause a well-grounded belief in the mind of a reasonable person.
So, if the other bank does not verify funds that would cause a reasonable person to believe that every check drawn on that bank is no good? If the girl I wanted to ask for a date in college did not answer the phone, I should assume she would have turned me down?
To me, it's ridiculous that this idea ever gained any traction anywhere.
