Caught in a situation where you need to opt between satisfying a High Net-worth Customer / PEP and Compliance issue, how do you go further?

Complying to rules and regulations is the right solution here. If you bend the rules to achieved that sales target, yes, you will be rewarded but other negative repercussions might occur such as mis-selling or mis-appropriation claimed by the customer in which will subject in disciplinary action or even termination of the involved employee. There is a reason for that specific guideline is in place to avoid such compliance violation. 

I think complying fully with the rules & regulations is the much more logical & legal route that one should go down on , simply because any violation would most likely result in some sort of penalty & legal backlash .
Now , if & only if this high-net worth customer's satisfaction will result in no such hit back , then i presume it'd be unwise not to go along with it .
However , one can not escape the ethical & moral dimension that always comes attached to such questions in the sense that even if no legal repercussions will materialize at the end of the day as a consequence to such placation , but , it resulted in an unequal manner of treatment between clienteles , one of them this high-falutin' client , & , the other , or others , maybe well-established customers , but maybe not that financially rewarding parties .
In this case do we abide by the rules no matter what , or , do we bend them backward over ( sort of speech ) to our benefits , especially when no harm will be done as a result !? ( That's the question ! ) .
