They’re just a bunch of bean pushers

I heard this one on an Allstate tv commercial about 20 years ago.  A customer was referring to the insurance adjuster, saying, “They really are kind and considerate.  They’re not just a bunch of bean pushers.”  This is a blend of “bean counters” (persons just interested in  the numbers of an issue) and “pencil pushers” ( persons just doing menial tasks).
