I have some questions about the movie "Unfinished Business." Could you help me?
1) Three guys are setting up a company, and one other person says: "You have a strong number set." What is a number set?
2) What does "tweak it in my mind" mean?
3) One guy is explaining to another what a sweetheart deal and a fluffer are, and he says: "They generally pretend to negotiate with another company right to the end, to make it look legit." What does "right to the end" mean?
4) In the same movie, someone says : "Let's drop these guys(people from another company)" What does drop mean here?
Thank you very much!
