Conversation between me and a lady at a bookstore.

Me: *Picks up book and heads to counter
Lady working at bookstore: Oh, hi!
Me: Uh, hi there.
Lady working at bookstore: *Laughs out loud* HAHAHAHA I read this book, HAHAHHA I was laughing so much!
Me, Unenthusiastic-ally: Oh, hehe..
Lady working at bookstore: Well, you see, I started to read this book while eating my lunch in the bathroom!
Me: Here, you can keep the change. Have a nice day.
Do you even know how much is wrong with this? Well, in case you didn't, I highlighted it in red. She read the book, while eating in the bathroom..
WHILE
EATING 
IN THE BATHROOM
THIS IS WHY I SUCK AT BEING HUMAN.
