A sign on the wall barring rap music from customer appreciation Tuesdays at Sam Jordan's Bar is shown in San Francisco, Calif., Monday, January 21, 2013.  Ruth Jordan, daughter of Sam Jordan, now runs her father's bar, which recently obtained landmark status.  The Jordans say Tuesdays draw an older crowd, so they cater the music to their tastes.
