A customer of mine, who had a vintage Ferarri in the garage, was not shy at all about spending money on audio stuff. He mentioned that whenever his wife asked how much such and such cost he would tell her the cost but without the last zero. She still complained bitterly.
This is pretty funny and probably true for most of us

...FOR WHAT I TOLD HER IT COST. " :-)
