Who knew self scan could be linked to my state of mind?

I was paying for a few grocery items at the (un-named) store this morning, and I chose to go through the "do it yourself" register... the "self scan" if you will. 
After I set my bag of onions on the scale, and looked up the item code... "Onions, white"... I saw that it came up as .94/lb rather than the posted .88/lb.
 
WHY did I look?!!  It was only three pounds of onions, so it is only .18 cents that I am talking about here.

I've done enough reading  {about how big giant stores will have many scanning "errors" that never get corrected, because they count on the fact that most people will not go to the hassle of bringing up the incorrectness when it's usually just a few cents} that, even if I tried to just ignore the "few cents" of overcharge, I knew I wouldn't. 
When a company does billions of dollars worth of business, and millions of people are paying just a few cents more than they are supposed to... well then... it needs to be addressed!

So I said to the Self Scan  Monitor Woman, "these onions are supposed to be .88/lb and it's coming up .94/lb."  
I had no intention of getting my 18 cents back, it just felt good to tell her... so that she knew that I KNEW.
But she smilingly came right over to my register with her badge in hand.

Which makes me think of the self-scan register at the local grocery store in the small town where my son & his family live... if you run into a snag there, the computer voice, which is about 50 times louder than it needs to be says "STAND BY!!! HELP IS ON THE WAY!!!!"
...this never fails to reduce me to giggles, and I always feel like standing at attention with a hopeful look on my face until someone rescues me!

Anyway, over she came and began to furiously touch all kinds of screen, describing to me exactly what she was doing, while I stood {helplessly} by.
"How much did it scan?"
".94"
"What is it supposed to be?"
".88"
...a few more touches, a few more times of clearing the screen, and it was obvious that what she was doing was not going to work. So she exasperatedly just typed in ONION and then asked me "how much is 3 times .88?"
Since I don't have the lightening fast calculating in my head speed that my husband does, my answer of $2.64 was not fast enough to suit her. "How much was the total scanned?" THAT I did not have to figure... but my answer of "$2.82" was still not quick enough for her.
She punched in, after ONIONS... $2.00... and that's what I paid for my produce.

"THERE!" she said, "you saved 82 cents... does that make you happy"??

"YES!! YES it does make me HAPPY!!!!"

Actually, I was quite content before all of this started too... and I only "saved" 64 cents.
But who's counting?
