I just wanted to reinforce your point, and point out the "remembering the good ones" bit. I hear a lot about remembering the nasty people, and I know it's true for me, too. I also know that for me at least the converse is true—I will quite happily do all sorts of things that technically aren't my job for someone who lets me know that they appreciate the work I do.

(And I always get excited when someone reminds people that production and editorial work really hard for not a lot of money to make books. So thanks!)

Also, I've had authors who seemed to believe that sending us a bottle of wine or a box of chocolates when a book was in stock was somehow going to make us forget that they'd been utterly dreadful to us during production. While the goodies were lovely, and certainly did mitigate the bad feelings, I'd have cheerfully traded my share for a little less hostility and a little more cooperation during the process.
