Jim asked John if John would like Jim to join John on a fishing trip.
John decided since Jim is Johns best friend, John went with Jim on Jims trip.
Jim and John arrived half way to Jim and Johns destination and Jim and John had to get gas.
John knowing Jims history of not being the honest person and a pathetic liar, John went with John on Jims trip because Jim had told John, Jim had money to fund Jims fishing trip.
On many occasions, Jim have a repeated history of going places without any funds and freeloading on his friends.
John asked if Jim had money for gas on Jims car. Jim replied to John that Jim does have the money and will be using his debit card.
A few seconds later, Jim swiped his card and found out his debit card didn't work.
Jim open the door and spoke to John that his debit card is negative and will need johns 40 dollars for gas.
John took out his 40 bucks and handed to Jim.
The face on John turned red and that was the moment John knew that Jim had plan this trip so John can pay for the whole trip.
This is the ending of Jim and Johns Jim John friendship.
