I think I know who you mean Matt!,It is the young guy who don't look 18 and does annoying bird noises into the PA.Also, If it is him he goes Welcome,Welcome,Welcome,Welcome,Welcome,Welcome, and that is it. The time he does that, he could have done the normal"Welcome to the Vampire, Place all bags and loose belongings on the exit platform and shoes MUST be worn".I felt like saying will you shut up and get back to the ausume music
