First and foremost, I agree with JoeRaj that a lesson have to be
taught,
BUT....
The fact that they used their credentials to try to pay for the
fare, I would have isolated them from those fare-dodgers.
That means probably they are genuine case, not trying to skip
your fare.
They are young, and probably foreigners. Humiliated and
scared.
We are already above 30 yrs old, already kena threatened from
young 'til old.
Seasoned old man vs fresh young girls.
Try to think at their level.
I strongly believe that if given the trust that they will
pay,... they WILL probably pay.
You want to know an example of the profile of a fare-dodger?
"Well dressed, not happy with the way you drive, do not give
instruction, and F*rk you for being so inexperienced. Then do a
quick get-away after paying short, or not paying at all."
always confirm the route bfore starting off the trip so as to
avoid
any disputes.................
