I reduce my fractions 100/100s percent of the time

It's something that was hammered into us since the second grade.
It's something that were were penalized for if we didn't do it.
Now we're chastised for doing it.
And criticized.
And told that we're doing it wrong.
I'm talking about reducing fractions.
Specifically, reducing fractions on the checks that we write.
The last time I looked, 1/2 was the same as 50/100. The last time I checked, 8/25 equaled 32/100. And 3/50 was the same as 6/100.
So why the fuss?
Don't bank tellers like math? Aren't they good at it? Isn't that partly the reason they chose that line of work?
My roomate does a pretty good job of managing the finances at my apartment. She tells me what I owe for the various bills and then makes the payment. Then she complains that the bank teller "almost refused to take the checks because you reduced the fractions". Perhaps the bank teller in question should pull out his handy-dandy calculator to double-check my math. Perhaps my roomate should try depositing the checks via the ATM.
I reduce fractions when I pay my regular bills (car, credit cards), and when I write a check to make a purchase. Aside from my roomate's complaints, I was called on it once.
A credit card company wrote to tell me that the amounts on the check didn't match. I explained to them that the numbers did match. In my explanation, I un-reduced the fraction, going step by step to show how I reached the numbers that I did. The credit card company finally agreed and accepted the check.
I don't reduce my fractions because I'm trying to rip off the payee. I do it because that's what I was taught to do with fractions.
Call me weird. Call me strange. Call me a freak. It's not going to stop me from being from putting my limited math skills to good use.
