## NEW MATH

Last week, I purchased a burger for $1.58. The counter girl

took my $2 and I was digging for my change when I pulled 8 cents

from my pocket and gave it to her. She stood there,

holding the nickel and 3 pennies, while looking at the

screen on her register. I sensed her discomfort and tried to

tell her to just give me two quarters, but s he hailed the manager

for help. While he tried to explain the transaction to her, she

stood there and cried. Why do I tell you this?
