Recently I came across a post on Slashdot where someone was charged .002 dollars for service, after being quoted over and over at a .002 cents rate. He got a bill where he was charged around $71 for downloading around 35 megs of stuff. At the quoted rate, he should have been charged closer to 71¢.
He called up Verizon, pointing out the error, and no one seemed to understand the difference between cents and dollars! He pointed out the difference over and over to multiple people on the phone, and still, no one understood him. The manager on the phone again confirmed that the rate was .002 cents, but then quoted him the price due at a rate of .002 dollars.

And a quick Google math check that Verizon couldn't seem to understand: http://www.google.com/search?q=.002+cents%2Fkb+times+35893kb+in+cents
