He was looking at one of our trades that wasn't ready on the day I originally showed it to him. When we scheduled the demo ride there was no mention of anybody else coming but him. He showed up with the whole family, some friends of the kids, a cooler and water skis with a tow rope.
I told him that our insurance would never cover a demo ride under those conditions without a 10% deposit with a signed, binding contract.
Once that ball was in his court he admitted that he just wanted to take his family for a boat ride on their vacation and he really wasn't in the market.
At the time I had a 35' Lightning and I took them for a ride after-hours without the water skis and cooler. They still send me Christmas cards every year and have never bought a boat.
