What does Margo ask Q when they are driving around, and where do they go?

Q lets Margo talk most of the time as he is in love with and finds her totally original and unlike anyone else he knows. At Publix, Margo sends Q to buy a weird list of supplies. She wonders why Q is so anxious and why he cares so much about ordinary matters in life. At Wal-Mart, Margo picks up "The Club," a car lock. She expresses concern that everyone lives in the future and not the present.
