This was the first thing I noticed when boarding a GN service for the first time. The words just don't flow together correctly and theres too much emphasis on the word "service"As far as I know, Great Northern services between Kings Cross and Cambridge/Kings Lynn have always had a momentary pause in the opening phrase "Welcome aboard this ... service...". I've heard various suggestions as to what word is missing, the most appropriate being my other half's suggestion: "Welcome aboard this unspeakable service...".
