Work-ups/ account of rain

Hi,

Still working on "Collateral"

Need your help with:

A killer is talking to the taxi driver, who he holds as a hostage:

"Go in, ask for Felix.
He's expecting you."

- "Felix. What does he look like?"
- "I don't know, I never met him."

"Who is he?"

"He's connected to the guys
who hired me."

"I don't get it."

"You destroyed my WORK-UPS.
Number four is due."

"What'd you think, night's over?
CALLED ON ACCOUNT OF RAIN?
Go in there, say you're me.
Score the backups."

A difficulty with WORK-UPS and CALLED ON ACCOUNT OF RAIN.

Hope you'll help me.

Thanks.
