Every rental and service is so optimized against scammers and abusers that being a perfect legit customer ie. simply want to pay, use the resource, then return the item or terminate the service, you're walking along the edge of a cliff. Annexes, penalties, fees and charges, exclusions, "sign this one more form, everyone signs it". Housing rental is another extreme example, one is simply unable to just get a job in new location and rent something long term.
