Oh for f*ck sake, the locals are far, far worse believe you me. Hearing a few F-words now and then is nothing compared to the kind of stuff that gets shouted on a regular basis in this "family friendly" town.
You go to any seaside resort in the country and walk around the back end of town near the busiest pubs/clubs and you will hear AND see a lot worse than the little knees up that went on down here.
