Update. 1K Voice acknowledged my email submission and said a supervisor would investigate my allegations. I think they took it seriously. That wasn't the only transgression that I alleged against those two FA's, but it was the only one that put, IMO, the safety of passengers in the vicinity of that exit door in some degree of risk if the occupants couldn't react promptly to crew instructions (think of US Air's rear doors being opened in the Hudson River crash). BTW, my safety card said don't open the wing doors in a water landing without crew instruction.
