Totally agree with this.

As for the hotel - first, she should contact the GM this morning to report the incident. If they didn't take her seriously and hope she'll forget it, he/she may not even have been notified of the incident. She should tell the GM that she has notified the police, do THAT first - do not let her be dissuaded from contacting the police and filing a report. Then discuss the 20 minutes (OMG, that is just totally unacceptable) lag until security showed up and the issues with the door. As for the last, I'd hope the police will ask to check that out, as well.

I've been assigned rooms with bad locks either on a connecting or front door. In each instant, I immediately return to the front desk and insist on a new room being assigned. I usually travel alone and have a list of okay/not okay for any hotel room including a working lock, secure connecting door (i hate those rooms) and no door that opens direct to the outside.

Try to always remember to flip the second lock, chain, etc
