Innumeracy a tale of $2.09
10 Sep 2002
I bought a small power connector in Radio Shack for $1.99. It came to $2.09 including tax. I initially handed the clerk $2 and a quarter which he entered into the cash register. I then handed him another four cents for a total of $2.29. This completely floored him, and it took some explaining that I now wanted 20 cents in change.
On to BJs for a few items -- one of which was a gallon of milk. The checkout person managed to give the milk to the person in front of me, and charge her (on her credit card) for it. The checkout person was completely flustered (I think that she had not been working long). I offered to give the $2.09 (for the milk) to the person in front of me as that would solve the problem. This solution was agreed. However, as I'm walking out, I observe that I have been charged for the milk as well (on my credit card). At this point, I decide to write off the money and give up.
John Allen Paulos has written a wonderful book called Innumeracy
that deals with the poor state of arithmetical knowledge in the general public. Definitely recommended.
