Oh My Gosh. I L-O-V-E when kids want to pay for their own item(s) and end up not having enough.
One girl bought those silly bands and paid in QUARTERS! and still came up 35 cents short. Her mother refused to give her the 35 cents. (Really?!)
Kid was lucky I had 50 cents on me. I felt bad because she was maybe eight and was so cute, even said "please" and "thank you."
I don't know where she got it from, because the mom was kinda nasty. She threw her basket on the counter and didn't remove her items, then threw her credit card at me.
I also once had a lady get mad because we had long lines and three open registers. (We have only 3 up front.)
She was all like, "Can you hurry up?! I'm in a rush! My infant is sleeping in the car and I left it running and he's by himself!"
An older woman FLIPPED out on her.
It was funny to watch, but seriously WTF lady?!
