I have sympathy with the 2 last posts. Yes, it is a real pain having to fill up before flying, which I have to do nearly every time even if I'm just doing a short local. Inevitably there will be a queue at the pumps, or they're shut for some reason or other. It all eats into your precious time that the plane is booked for, and is a right fag if you have non-flying friends with you who have to hang around.
Not to mention the fact that some planes I've flown have been reluctant to start again after a stop at the pumps.
On the other hand, arrive with four of you for a PA28 that has been filled to the top - you've had it.
