When your changes keep being reverted and you finally discover the 'experienced' contractor has been using rebase and 'take mine' in git merges.

Yeah, gotta few guys who have their prefs set to always push when committing. Why?!?!?! And then they get a list of conflicts and say to themselves, "well, my stuff is more important.... I don't know how to merge, so I will let the senior Dev do that". Oh, and wtf?!?!?! .... Please setup your ssh keys so we can use submodules... I don't have all day to keep merging
