Good calculator

Example:
I went to a store yesterday and bought something that amounted to $9.30, i handed the 16 year old girl cashier a $10.00 bill and thirty cents.
She said to me ''That's too much, sir''.
I explained that i wanted a dollar back in change so i could use the car wash next door. (We have dollar coins here in Canada).
She gave me a surprised look, and i told her to enter the amount i gave her in the cash register anyway.
She did so and the change came out to exactly $1.00.
She couldn't believe that i could do that calculation in my head so fast!
I said it's part of being old and being taught a different way in school.
You get this same thing at drive-threws with the younger people, but surprisingly, never with the older employees.....


Or giving them change so that you don't get back any pennies, nickles, or dimes...

It's not that the kids are not capable, I believe the teachers are not empowered with discipline as much anymore-and that the culture has changed where people lay responsibility elsewhere, or cannot focus because of entertainment & discipline levels. Many of the women in my family are teachers. Some of the inner city public schools in San Antonio are so depressing with high-school aged children barely able to read.-and mom is supposed to teach biology, chemistry, to students with those capabilities.
