Provocative sign: "Language Line"

       "Language line"--discovered on a wall near a nurses' station at Kaiser Hospital.  What's that?  Somewhere nearby, another phrase, "interpreter services available."

       Oh, a phone line to an interpreter to help translate, communicate with patients.

      But the phrase has other suggestions in it--"language line":  Wait in line to get a language?  Or "language line":   like clothes?  all of 'em hanging out to dry?
