You call Leonard desperate for him to answer and you flatter him... to finally go to the point and ask for $2500 dollars

Leonard replied incredulously "No?? Why on Earth do you need 2500?"

You laugh awkwardly and say it's for an... Escape Room? He frowns and says in disbelief and yell "You're joking right? What kind of ESCAPE ROOM COSTS $2500?!"

Scared, you whisper to him "Prison" and there's a moment of silence in the call but then Leonard replies "I'll be there in 10... idiot."
