MOT & Service Price Question

Hi, my girlfriend just got her car MOT’d and is annoyed at the price. I wasn’t there and know nothing about cars so I don’t know if it is reasonable.

It’s a 2018 Citron C3.

She asked for a half service (not sure if that’s the right name), they did a full service, and when this was brought up the guy apparently went “oh, sorry about that”.

Also, she’s not sure why a spark plug costs £85.00.

Can someone with a bit of knowledge confirm if this is reasonable? Thanks!
