Yeah, actually my friend had trouble with deleting a pesky folder and changing permissions using Get Info didn't work out and all sorts of crazy things. Nothing would work, couldn't rename it or anything, but I am one that doesn't find it a huge deal to go in to Terminal and take care of it that way. I never did figure out what the real deal was as I'm no Command Line God by any stretch of the imagination, but throwing a couple sudo commands at the problem took care of it.
This was an earlier version of OS X when things were still a bit flaky. I haven't experienced this since, beyond maybe trying to delete something that's still in use somewhere or something stupid like that.
I playfully that submit most college kids that would drop in to command line to delete the trash for a friend are products of the hacker's portrayal in The Matrix movies and trying to look cool, but i digress...
