yeah I have heard of this stereotype. my dad does home improvement and house painting. Are you familar with the mt. washington or roland park area? there is a big jewish population there. my dad has done work there. Once when i was a little girl i went with him to a job. he told the homeowner the cost. my dad asked him something like, "does that seem fair?" the guy laughed and said,"yeah, it seems kinda cheap though, and thats coming from a jew". i was too young to get it. but didnt see anything wrong. he told a joke and they laughed. i got older and discovered that is was a stereotype.
But "jew him down"? really? it makes it seem as if being a jew is something bad.
