I went out to a focus for a fleet company a few months ago, had to change a headlight bulb. They rang me saying it was in ATS (iirc) and they wanted to charge a fortune in labour to remove xyz to get to the back of the headlight lol. Sometimes people just can't see the wood for the trees. All you have to do is undo a couple of bolts at the top of the headlight and pop it forward to gain access. But for some reason some people just think "gotta get to the back of the headlight" and worry about stripping the entire front end off to do so.

Seen it a lot with transits too, drivers saying they can't get to the headlight. 9/10 when you show them it's two bolts (torx but even a ham fisted driver with a flat screwdriver would do it as they have a slot for it too) and pull the light forward and you've got all the access you need it all seems very obvious.
