I just started watching. I heard two effings in the first 5 minutes.

At 1:46, a man is chasing a Santa Claus or Father Christmas. The Christmas character is singing. After he sings "Jingle Bells" the chaser says "OK, come on". Both lines are subtitled but between these two lines, the chaser, frustrated at his inability to catch Saint Nick, very clearly says "effing...". This line is not subtitled on UKTV Play. No doubt about it though, it's definitely "effing". I would have added the word here too if I was working for Red Bee.

Admitally, there is a very small possibility that I might just be hearing what I want to hear.

It's such a cacophony of noise, it's hard to make out what's being said. And I still think it's very unlikely to be that word considering the nature of the show.

And it's worth pointing out the character of the "chaser" is Polish, and it's possible that he's saying something in that language that sounds a bit like it.

And if you were working for Red Bee... would you really have added the word when told you were subtitling something going out at 10:30 in the morning, even if that is what you thought you heard?
