Lester the Chauffeur.
What was the deal with Lester?
Why did he try and black mail his boss?
Also how did he knew about the maid's status about being in the country illeagly?
Money surely had a big part.
He easily could have found out somehow, including by checking her room or her leaking it out at some point. The movie may have said exactly at some point, but I didn't see that part if it did.
