If something is marketed as "unlimited", I don't think there is such a thing as "wildly excessive use". This isn't a competitive eater going to an all-you-can-eat buffet and being mad about getting kicked out. It's a business using a service in a way that's seemingly in-line with what they paid for.

A man walks into whorehouse at half past seven, inquires about prices, and learns that it’s 250 per night, per person for the room. “Everything they consent to is available to the customer” says the proprietor. Gladly he pays and climbs up the steps with his hand clasped tenderly, finally landing upon a plain pink cushion, whereupon he proceeds to fuck the absolute shit out of his companion for six full hours. The brothel quakes in rhythm with their dual shrieks of ecstasy for the full duration.

As he begins dressing himself across from the nearly comatose prostitute, the proprietor returns, requesting two hundred and ninety dollars for the extended stay and sixty for the damage to her employee. It was at that moment that the man realized that the madame was a 70 foot tall crustacean from the Paleozoic era. He yells “goddamn Loch Ness monster, I ain’t giving you no three fifty!”
