What does it mean to pay in a funky way?
None of this is discussed with customers in a candid way; as a result it can feel very off putting. It's one of the things that bugs me about modern finance. It's too busy building itself into a governmental reporting mechanism, and far too prone to overreach through the exploitation of sanctioning mechanisms.
It's one of those "can't have nice things" sorta bits.
Of course, this doesn't mean your customer service agents should never be helpful and forthcoming, but it's easier and less risky to tell them to say nothing and burn the odd legit customer, rather than risk being on the wrong side of AML legislation.
