...Disagree all you like .....
I will and I do - often with members on this forum whom I respect immensely
.... but judging by this thread and zillion other examples, you'd be in the minority. .....
Again I disagree. Yes, I would be in the minority within a group that enjoy posting about such "scams" and "rip-offs", but amongst the wider travelling population I am not so sure.
If you closely examine such events, the culprit is usually poor or shoddy work, not intentional scamming. (again, am not talking about those overseas places where you get hit with 10,000 bucks of repair bills, etc.) And in the same way many people blame "the government" or some big business for some sin, at the end of the day such organisations are made up of individual people (the workers).
In the OP's event, an incorrect reading was taken of the odometer which resulted in an excess mileage charge. Do you really think that worker, the guy (or gal) who notated that figure, deliberately and cunningly changed the number to a higher figure? Do you think they "got a cut" of the extra charge? (less tax, etc as this is recorded income for the company) Do you really think that the "boss" of whichever car rental agency it was, sits down his staff and instructs them to falsify the records, and tells them how they will split the money they thus steal? Do you think the company manages to get the excess payments out of their accounting and deliver the staff paper bags of cash? And of course to identify these, they run a secondary system whereby they have one set of data for what the real rentals would have been, and another set of the fraudulent extras charged? With of course details of which staff member committed exactly which rip-off, so they could all fairly divide a "bonus"?
Unfortunately, I actually do think that some people would believe this....
