That you'd be advertising bbfs services on the behalf of other women who work for your agency.  They can do as they wish, but if you're advertising bbfs on their behalf, you'd better be sure that these women actually consent to it.  

Offering that service on behalf of someone else (any specific service on behalf of someone else, really), is an instant red flag.  Services should be negotiated between the client and the actual provider, not by the agency.  

Unless you didn't understand that the service being requested was in fact bbfs.  If that's the case, you're forgiven.
