On a job I was on we had an inspector tear a box off the wall (using those plastic anchors)...he said it didn't appear very secure to him!...guess he didn't like plastic anchors.(not my work, thank you)....when the electrician started to complain he opened his briefcase showed us his very dog-eared mechanical, electrical, plumbing, and building code books and proceeded to show us about a dozen microscopic code violations in all the trades...he assured us he wasn't there to nit-pick us and wouldn't bother us with citing us and charging for a reinspection, however he was sure we agreed with his 'poor securing' position for the elect. box. !! I had to bite my tongue to stop from laughing.
