I once did a solo that went 3.5 hours with them bringing in higher and higher pressure senior folks.  I say "No," about as well as any experienced real estate agent, but they would not let go.  Finally, they said that I should sleep on it and contact the head honcho with my answer in the morning, where I would get my gifts either way.  I then walked around the immediate area and found a great lunch spot.  In my "tour" of the neighborhood I was offered drugs 3 times, observed "the stoll" complete with hookers of at least 3 gender profiles, several folks sitting on front steps nodding out,  and saw the police sitting in patrol cars eating lunch.  The next morning I saw the head pressure salesman and told him my reasons for not buying, including what I had observed in the same city block as the "luxury time share."  He screamed at me words to the following effect, "You come from Washington, DC and claim you have never seen a place with drugs and hookers?  You lie!" He threw the prize vouchers at me and stomped away.  The receptionist who saw and heard the whole thing looked at me and shrugged.   I so wish that that had been a recorded shop!
