Cambletown has a formidable reputation and dislike of strangers especially yotties perhaps they preffered fly boys , to be fair I think things have moderated from days of tying up to pier and locals spitting down on you , not safe to walk around alone at night . not the usual scottish welcome
I say "fly boys " as I guess you perhaps were stationed at us airfield near Cambletown.
Next time in helensburgh give me a shout , and you can come and meet the helcats and share some scottish swally
