So I am going to give you all a lesson on why math and basic thought is important. Earlier today I ran out to the supermarket because my mom and dad wanted rotisserie chicken for dinner. I picked it up for them, stood in the only line that was open at my supermarket and paid with a $20 bill.
When I get back home I go through my change and realize something wasn't right. I remember the total at the store came up somewhere in the $11 range. But yet I had $13.65 in my pocket. I checked the receipt. The total was $11.35, the change due back was $8.65. But yet I had $13.65. A ten, three singles, two quarters, a dime and a nickel.
I figure it out pretty quickly: the cashier accidentally gave me the wrong amount back. She meant to give me a five, she accidentally gave me a ten instead. It happens when you are in a rush. I want to do the right thing so I decide to head back to the store. My mom on the way out tells me since I am going back to pick up a thing of butter.
I head back to the store. The cashier is busy so I decide to pick up the butter first and then get into line to give the ten dollars back to her. I eventually get to the front after picking up the butter. I explain to her what she did and that I was returning the ten to get a five back.
She tells me thank you for doing that. She takes the ten and puts it back in her drawer. She then proceeds to scan the butter and doesn't give my the five back. I figure she was just going to deduct the price from the five and give me back the remaining change.
Instead she tells me the price without giving me the five back.
I point out to her that I wanted to use the change I was originally owed to pay for it. It was somehwere in the $3.30 range. I didn't have enough cash on me to cover the butter and I forgot to bring my card with me.
She then says "Oh"and proceeds to punch-it in. She hands me back the new change. I had back home to eat dinner. When I get there I realized I had over $6.00 in change in my pocket. I didn't understand how. The three singles from the original batch of change I had left at home before going back out. I should have only had a buck and some coins leftover.
I then realized she had deducted the price of the butter from the ten I had returned to her despite me telling her she had given me the ten by mistake.
If you have any kids at home, tell them to stay in school.
