I had the pleasure to observe a similar action when I worked a female medical prison.
Two Nigerian sisters doing time for smuggling drugs from Nigeria to the US. A member of the Nigerian Embassy escorted the husband in to visit his wives, they were sisters. The Embassy official had been vetted by Central Office and the Nigerian Embassy vetted the husband's I.D. and passport.
The two men were processed into the Visiting Room first. My job was to observe the visitors as the black, female case manager did the strip searches on the inmates and brought them into the secure Visiting Room. When the women came in they walked over to where the two men were sitting and talking to one another. The women got down on their knees, hands folded in their laps and heads bowed down.
The two men kept talking totally ignoring the women for several minutes. The women stayed down and bowed.
When the case manager got over to where we sat for the observation, she had had her back to the situation the entire time. When she got to the desk I said "Look at that will ya. You American girls don't know just how good ya'll got it livin' in America". Just to needle her. She sat down staring holes through the men across the room. If she were Supergirl she would have ignited them into flames.
After a good 5 minutes the husband acknowledged the two women. They stood up and bowed again and then took seats one on each side of the husband with the embassy official sitting directly across a small table from them.
The visit lasted about a hour. When it was over the women stood up before the men stood and bowed their heads. The visitors were processed out first and left the institution. I waited outside the Inmate Entrance for the case manager and the two inmates and we escorted them back to the housing unit.
After it was all over I walked by the case manager's office, cracked open the door and started singing " America, America GOD shed his grace of thee and . " "OH, SHUT UP I SAW IT." she interupted with.
"Yep, Yep, Yep Ya girls got it good here". My last words as she threw a book at the closing door.
