People can be funny creatures.
As examples, some people...
Never volunteer for new tasks, standing firmly even when the tasks are quick and easy.
Refrain from giving compliments, removing encouragement of such unwarranted expectations.
Hold their good ideas in secrecy, protecting them from potential criticism.
Demand the impossible, setting other people's bars at lofty levels.
Leave messes for others to clean up, leaving clear signs of services required.
Display their anger as clearly as possible, feeling free to unleash body language.
Point fingers and place blame, supporting the need for others to jump to fix problems.
Frame theirr questions with confusion, confounding others at every opportunity.
Delay as a matter of habit, expanding attention to the value that they just might deliver.
Refuse to serve in any way, stepping aside to allow others to fill those lesser roles.
