Bouncing off the Romper Room walls

Teen girl walks in with a four-year-old girl. 

Teen: How much is a small coffee?

Me: $1.66

Teen: (Digs in purse. Stops. Looks at me.) Do you think it would be a good idea for her? (points at little girl)

Me: No. She probably won’t like it…

Teen: Oh, she likes it. My grandma gives it to her.

Me: Well are you baby sitting today?

Teen: Yeah.

Me: Then you don’t want to give her coffee.
