Once had a manager who would refuse to review anything on the basis he "didn't have enough time". Not just code reviews, but also customer comms, support messages, documentation etc. - anything that it's good to get more than 1 set of eyes on. This was a small startup so me working pretty much solo - it wasn't like there was anyone else able to review anything like this.

Fair enough, you might say. He trusts me. Just put it out there.

...but then *as soon as* it was published / sent / committed / whatever, he'd then magically find 5 minutes to glance through it and point out how rubbish / unhelpful / ridiculous the work was, and how it should have never gone out in the first place, and why didn't I read through it before sending as I'd clearly realise how stupid this was.

After a few rounds of this I actually flipped out on him in the office, called him out on his BS and told him to think for 2 seconds about how ridiculous this situation was. In fairness to the guy he did back down, take note and it didn't happen again, but damn, those times were some of the most frustrating of my career to date.
