I'm currently stuck working with an internal collaborator on a project that I was originally supposed to just provide technical advice to. It grew to them trying to dump the work off on me and using all our equipment and reagents. After explaining to the collaborator that the only thing in the world that mattered more to me than his project was everything else in the world, he took the hint and started working on it himself. But the cheap fuck is using all our reagents and kits to do the work, I don't think the boss man thought this would be the case but I've got to bring it up to him. He may roll over on this but "our" collaboration is now at a standstill until some stuff for the project is ordered and the doucheknuckle wants us to pony up the money for it.
There is no way in hell I'm going to pay for stuff we might not even use in the lab to help this person out on a one off project. At this point, they need to put some skin in the game, so I'm using the slow roll approach and conveniently forgetting to order what we need until they get a clue and do it themselves. This has been frustrating, I don't have time to drop everything whenever you deign to show up and am getting pissed off when you forget to answer my emails for a month. This collaboration will net me nothing, I will help you produce what you need and at best end up buried in the middle of the authorship if even that. I've got other fish to fry.
Speaking of frying fish I need to go catch some catfish.
