Would you go?

You have to take off at dawn to pick up an Angel Flight patient 200
miles away, so you call the FBO the night before to have the airplane
pulled out and fueled.

When you arrive at the airport, you find the fuel truck parked in front
of the airplane, blocking it. The FBO is locked up and no one's around.
Checking the gauges reveals that fuel has been added. You call the
FBO's number, but all you can do is leave a message on the answering
machine asking what's going on.

It's time to go; you could push the plane away from the truck and taxi
away, but now you're wondering: did they block it for a reason? Is the
fuel contaminated? Did someone notice something dangerous about the
plane that you don't see? Did you forget to pay your fuel bill?
What???

In the event, I did an extra careful preflight, took large fuel samples,
did an extended run-up and took off with no problems. Would you have?
