What juice does the man order?

W: Anything to drink, sir? We have apple juice, orange juice and lemon juice.
M: OK, I’ll have a glass of orange juice.

M: Susan told me you were on a diet. How much weight have you lost?
W: Well, to start with, I weighed 160 pounds. During the first two weeks I took off 10 pounds, but then I gained 3 over the holidays.
