only suggestion I would make is for there to be advance notification of delivery of fuel - we have never run out of fuel, and I know you use historical consumption metrics as part of your service schedule. it would be good for us to know when you are coming - say a week or even a couple days in advance. that way we could make sure out turn around for your truck is not obstructed - otherwise the driver needs to back up our driveway which is somewhat tortuous - although your drivers have always been able to manage it well enough.
