Helping some guy bogged on Pondalowie beach in SA retrieving his tinny with the tide coming in cost me a $3500 front diff for the cruiser plus the next days charter I was booked on - didn't even get a "sorry mate". The diff shouldn't have gone in the first place but what made it worse was a mate in a 20 year old Pathfinder pulled us both off the beach. Ever since I've been happy to help but a lot more cautious of potential damage to my vehicle.
