I'm also guessing there's some compliance mess involved. I can't imagine that all banks have some moral stand on not banking for marijuana businesses. My guess is that processing charges for them constitutes some from of "providing banking services for illegal money" since marijuana is still illegal federally (and most large banks tend to be multi-state). This is the bank passing the buck on that. "We didn't violate that law, the customer lied to us."
