I didn't hear the whole story but I heard a quick news flash about a Fire House that woman who were working there were also were working as escorts!!!
That is very clever. Great way to meet clients.
It is possible you are thinking about a situation in Washington DC. According to Saturday's Washington Post:
"Authorities are investigating allegations of sexual misconduct within the D.C. fire department, including reports that at least two employees were running a prostitution ring, officials said yesterday."
I would not characterize this as women working out of the firehouse. Given that this arose over a sexual harassment investigation it is more likely that a couple of firefighters are supplementing their income by running an "agency."
Of course, if it were the female firefighters working at least there would be good reasons for a no-show
