You scold yourself for being so stupid. She's only an old woman! She might be crazy, but you're a young man! You'd easily take her on.
Whilst you continue to silently rebuke yourself, she comes up to the counter. She has a video copy of 'An American Werewolf In London' under her arm.
"How can I help you?" you ask.
"You've got to help me, Sir!" she cries in a posh English accent, which sounds like Judi Dench's voice.
"What's the matter?" you say.
She takes a deep breath, her eyes welling with tears. "It's this video tape! I rented it the other day!"
"Are you returning it late?" you ask, slight authority rising in your voice.
"No!" she practically shrieks. "It wasn't a movie! It was filled with trailers. Thinking they came before the movie, I fast forwarded the trailers. I counted twenty of them, before I lost my patience. I turned the video off when I came to 'Ladies In Lavender'."
"Well," you muse. "I'm terribly sorry for this inconvience. Would you like your money back, or a free new release rental?"
"I haven't finished!" she explodes. "After the last trailer, I changed! Seeing 'Ladies In Lavender' with Judi Dench turned me into her!"
You are completely stunned. The old bag is crazy! What do you do with her?
