Friend accompaniment at JCP (UC)

Hopefully a quick one, sorry if posted elsewhere.

A friend has been called into JCP tomorrow re. their UC. They were prepared to go alone but have anxiety etc. so I've offered to go in moral support (to just observe but keep schtum), but I've just thought - do we need to/is it better to advise in advance or if we just turn up together are they likely to accommodate without issue (again, assuming I play no part in the thing other than being present)?

Thanks!

Thank-you, David. I was thinking if JCP aren't going to mind then keeping it more casual might avoid giving my friend another thing to stress about, but I'll weigh up the risks and depending how they are consider suggesting messaging or help with writing a quick note - much appreciated.

I experienced this with the JC guards, I went with my step daughter once and they absolutely wouldn't let me go with her and told me to leave! Thankfully she was ok with it but it was pretty rubbish of them.

Quite, I expect most if not all of us would find that totally out of proportion. Funny I was discussing with my friend how they want to have a friendly chat and be your mate, yet wouldn't respect my friend enough to give them a private room without leaving the door open to the lobby, as if there's any real risk posed by a regular one-to-one across a desk, especially while security roam about mere yards away (incidentally, bored out of their minds because nothing ever happens!). Hypocrisy and needless securitisation; such is the holy DWP eh, law unto themselves.
