I wonder about two things:

1 - If the departure amount is recorded, do they refund you anything if you bring it back with more fuel than you left with?

2 - Has anyone complained to the weights/measurement authorities of the states?

Also, what a stupid name "virtual reader". It makes it sound unreal and unreliable - this is the last thing you want the customer to feel when you try to charge them. Can we pay the charge with virtual money

Thanks.
