I attended a cousins party this afternoon and on the way home stopped at a rest area on the Thruway. I purchased a package of crackers for Susan and I. The crackers cost $1.09 and I gave the clerk a 5 dollar bill. Before she gave me the change, I handed her a quarter so that I would not have a pocket full of change ($.91).
The correct change should have been four one dollar bills, a dime, a nickel and a penny ($4.16).
The cash register told her to give me $3.91.
And the clerk could not figure out in her head how to give me the correct change so she gave me $3.91.
American education is in serious trouble and I can now prove it.
