Just to add a point of irritation, at least for me.
Umpires who register, barely attempt to obtain a minimal amount of training, skimp on uniforms and equipment, only make themselves available for the highest pay-level of games, refuse to help younger umpires, refuse to help their association unless receiving top dollar.
However, many of these putzes will be some of the first to declare they only work the higher level (NFHS/NCAA) of games as if that is a badge of honor.
Then there are the braggarts that don't work SP because that is a "beer league" situation. Those folks should visit OKC during the Battle of the Borders and see how those players feel about that opinion.
