Perverse is a bit strong :-) To be understood as killing the 'billing problem'...

[inanutshellus]

One could say it kills problems, or headaches, or anxiety. But what does it create? It creates bills. "Perverse" seems like a pretty good descriptor.

perverse: adjective (of a person or their actions) showing a deliberate and obstinate desire to behave in a way that is unreasonable or unacceptable, often in spite of the consequences.

Perhaps "ironic" would be a better word. :-)

ironic: adjective, happening in the opposite way to what is expected, and typically causing wry amusement because of this.
