I have been approached on two occasions by volunteers this week who said they were appalled to hear two volunteers shouting and swearing at one another on the station platform. Although there weren't many visitors about, it was clear to them that this altercation was heard by more than one passenger. This is unacceptable. We all have disagreements on occasions with one another but any such arguments must be carried out away from the public gaze. We are the "friendly line" after all!
