Hahaha, she knew... that's why she didn't warn you about any of the trouble you'd get into at the pub that night. She knew you'd never pay so made up the most mundane things she could....
It is amazing that not only the fortune teller industry ever started, but that it caught on and still exists today.... they must know something about the future mental capacities of mankind. We might be in trouble.
They know about the gullibility of mankind that's for sure!
I would be surprised if she knew how to get out of her own clothes at night!
