I got into a cab some years ago. The driver seemed quite unhappy about me saying "to the airport, domestic terminal please".
He mumbled something and drove off.
I then noticed he really smelt bad, he hair was oily and unkept. On the passengers seat was his lunch, MCdonalds. As we drove he had a burger in one hand and a drink between his knees, he'd occasionally fumble with a few fries. At this point he had one hand free.
He then lit a smoke. now no hands free and steering with his knees was difficult due to the drink.
We hit some traffic on the motorway so he exited and started winding along the minor roads.
You can imaging it was all a bit nerve racking..
The situation improved very quickly as he then ran out of fuel..
The cab lulled to a stop.
I promptly opened the door and walked off with him yelling "you havn't paid", just as another cab came along.
The other driver was happy to drive me to the airport. He didn't eat smoke, fart or pick his nose and spoke english, even used 2 hands on the steering wheel.
For this he recieved a very healthy tip more than equal to the value I should have paid the other driver.
