Of his money. I'd offer two options, I drop you at the airport where you can get a plane ride or a rental car. Option 2, you can be my camp manager for the week.I think it would be worth $4-500 bucks to put him on a plane. I'd probably pay that out of pocket to keep going.
Of course this only works if it is my truck we drove out in. Otherwise, I'm renting a vehicle.
Blind Squirrel, Sorry to hear it didn't work out. I'm sure you have your reasons for calling it. I also hope the fellow understands what a shit sandwich he served you. Expensive lesson.
