If you were a passenger hiring a boat to take you from point A to point B, but with no intention of paying, why would you announce that out of the blue only 100 yards from point A? "I don't have to pay you nothing" sounds like it would have been in response to a demand for payment and not something the passenger would have just volunteered before the boat arrived at its destination. Also, if you were a boat operator agreeing to take someone from point A to point B, putting that person ahead of others in exchange for payment, wouldn't you request payment up front? Last, what is the link between the passenger who announced his refusal to pay and the boat tour operators who have a grudge against the Koehne? How would the boat tour operators learn about the passenger's refusal to pay then somehow spin that around against Koehne? This whole situation is bizarre.
