The part where customer A is paying for a connection to "the Internet"
at some data rate, which includes the network run by customer B.
REGARDLESS of whether B pays the same service provider.

If the service rendered to A is changed by B's payment (or lack),
that's a conflict of interest.

To remove the conflict of interest, you either have to fiddle the
definition of what customer A is buying, turning it into something
that would not be obvious to an ordinary person or you have or you
have to allow B to engage in settlement free peering if they want to.
Or, counterintuitively, pay your own transit provider enough to handle
any capacity A and B together care to consume.
