"Are you gonna spend it at the casino?"

I'll refer to K, as Kat from now on and J, will be Bub.

She makes me friggen laugh. I walked into the livingroom and she tells me that Bub was drawing with the stinky (sharpie) pen. As I was looking for permanent marks I found a paper that she was drawing ticket-stub-looking things. She fessed up to using the sharpie. The pen had gone thru the paper and stained grandma's tv tray. I had her wipe the marks with a wippee, she realized that wasn't working. Her and grandma had a sit down to figure what to do next. Grandma had some cleaner that took it right off, and for her cleaning time she was charging Kat $1. Kat looked puzzled, and asked "are you gonna spend it at the casino?" Grandma is really good at keeping a straight face, I am getting better, but I had to turn my head.
I 'm thinking the casino remark is from a few months back, Kat had given all her quarters to Grandma in exchange for dollar bills. She was heading to the casinos in Vegas. And being considerate, she wanted to know if she'd like a dollar bill or change. Too funny.
