How dangerous is smoking at a gas station?

I know that gas is volatile, but it seems like it would be diffused enough that there wouldn't be a high risk. Just wondering if any of you folks can clear this up for me! Thanks.

Gasoline vapors will ignite at concentrations between 1.4 and 7.6% in air. This concentration is guaranteed to exist *somewhere* near fueling operations, if you light your cigarette in the same location, you are going to have a very bad day. The odds of this are probably very slim, but if you're unlucky you'll probably be on fire for the rest of your life.
