I didn't think it could get worse but here we are: at about 42%, we learn that the protagonist/narrator only because a cop because of what happened to her as a teenager.
Obvious inference: she was assaulted.
May be wrong, but if it's correct, the whole "let strange man order her drink and bring it to her, giving him opportunity to tamper with it" is even more egregious than it seemed at first (it was bad enough already)
