I don't know about PA, but here in Ohio the pumps are all covered with these big warning stickers about not doing this or not doing that.
I'll have to say though, I for one am not real good at paying attention to the warnings either. Talk on my cellphone all the time at the pumps, although MYTH BUSTERS proved that spark source didn't exist.
Glad you're OK and no real damage, maybe now the rest of us will pay attention to those big red and white stickers that say DANGER!
Now I just have to stop the wife from lighting the gas grill with the lid down, under the patio roof!
