Locally on occasion it was the common practice when "in service" to leave gas money for the driver. I know that the individuals if savvy can get a tax credit for mileage for service (and I was once told mileage to and from public talks could also be included). What I am curious about is do people still give the driver money for thier trouble? Especially those who are chronically unable to drive themselves. In the territory I used to be in it was not uncommon to drive 100-300 miles if out all day, make that 3-4 times a week and look at that gas bill, not to mention wear and tear on perfectly good vehicles.
Or are witnesses too inconsiderate to do that anymore?
