Got it, but now your situation has turned anomalous: You seem to be the only user here with an apparently default "Quit Finder" option in your Menu Bar. (I haven't got one in 10.6.8.)
Grelber is not the only one here that has the Finder > Quit (also command+Q). I have had it for several years and honestly do not remember in what version of OS X it began in. FWIW I have found it very useful when some Finder operation gets hung and use it reasonably often. It is a useful tool.
