Discretion is very important in this business. I never call back a client without permission and don't send text for him. Sometimes the wife or GF pick up the phone and see the incoming message. But it's two way. I hate when a client arrive in my building and call me from the lobby for the buzzer and apt. number. Call or text me from the car or from the street is right. Call me from inside of the building is very unprofessional.
