we went on Referrals twice and bought the second time. If you want to keep it as short as possible ask to skip the breakfast and go straight to the sales meeting. You are only obligated for 90 minutes, when the 90 minutes us up tell them you have met your obligation and are not interested. It will take about 15 more minutes but if you are polite but firm with them you will be out in about 100-105 minutes. total. That's what we did and it was fairly painless.
