CT has a point and its not funny, however most of us (including me) do not get that Chinese auction might be offensive. wherever that term came from sort of lost its meaning.
I was once speaking to someone on the phone and she says to me that I should “Jew Down the Price”. The person had no Idea I was jewish and didnt even think that was offensive. I do sales and normally you are supposed to be composed over the phone (They called me , not a cold me from me) and I told them how offensive it was to say “Jew down the price”
