I read that slightly differently, although it is poorly written and open to various interpretations.
If she has been / is being stalked, then the police will have advised her to keep a detailed log of any incidents. This is important if the matter ends up in court as it is far more believable than a lot of vaguely remembered events. Therefore, if you make a booking and then just don't turn up your details will go into that log, and they may at some later date be turned over to the police for cross-checking. However, the police will not be interested in each individual event as it happens. So, if you are a timewaster, expect to go into her event log, but the police will not necessarily be knocking on your door as a result.
Having said that, the whole business would be enough to put me off; I can't be doing with that much drama before we even start.
