The third purchase failure

Yesterday I went with Tomek to Kielce (a city 180 km, 110 miles from Warsaw) to buy a VW T3. I phoned the guy who wanted to sell it at noon, we decided to meet there at 8 PM. At 7:45 PM he calls me and asks me if we left Warsaw already. "Yes, we're 32 km (20 miles) from Kielce at the moment", I replied. Why did he call me? Because he sold the car.

I don't know if I am trying to buy the car from idiots. This one is surely an idiot. He could tell me that someone is going to see the bus, I'd leave Warsaw later or stay at home if he sold it. Now I guess he needs to refund me the trip costs since diesel fuel in Warsaw is not free.
