Here is a link to a YouTube recording of a man arguing with a Verizon customer service supervisor and the customer service manager that they overcharged him the quoted rate for a data connection while travelling in Canada. They kept saying that "$0.002 per kilobyte" was ".002 cents per kilobyte", which is obviously off by two orders of magnitude. The result was he was billed some $71 rather than 71 cents.
The scary part was that none of the people he talked to ever "got" it. They (especially the "floor manager" he talked to last) seemed to think that because the number had a decimal point in it, they were supposed to say "cents" rather "dollars". Just listen to it. It's unbelievable.
Those who know me know I share Neal Boortz's and John Stossel's views of the complete failure of government education. Now I don't know for certain that these people were government educated, but I'd bet money on it.
