'For Christ sake's James! You're making bloody hard going out of this collar!'
[Transcript from Episode 1 - SOURCE around 65 or so lines down from the top.]
This is from The Crown on Netflix, I was wondering what it might mean, I googled it and nothing of help came up.
It sounds really awkward as well, don't know if this is dated usage or something else.
Context: Location: UK, Time: 1947 London.
The king is getting his collar done up by his butler(James), and the King is getting annoyed at James because he's taking too long or something. It's hard to describe and I can't find any clips of the moment, sorry.
EDIT: Found a clip, here it is. - Time-stamp: 1:00
