The gas station owners will not buy the temperature compensated
meters, even if the pump manufacturers offer them - it is not required
by law, and they love the thought of selling their gas 1% to 2% short
in the summer. Added profits, baby...

They did a radio interview on the subject of selling gas short out
here, IIRC it was Al Rantel on KABC. One of the gas pump makers was
told by a major customer (chain of independent stations) to take the
compensated meter mechanism out of the catalog totally, they don't
even want it visible as an option. If there was evidence it was even
available they'd buy their replacement gas pumps from one of the other
major makers.

But the temperature compensation IS required and installed on the
wholesale metering when they load the tank trucks. We (the gas
station) don't want to get shorted when we buy the gas, but it's just
fine and dandy to short the retail customer when we sell it...

And there's a wrinkle you need to watch out for - chipped gas pumps.
They change the ROM chips in the pump totalizer, where it counts the
volume pulses from the totalizer and rings up the price display.
Perfectly accurate up to the 5-gallon and 10-gallon test points where
they'd get caught by Weights & Measures, then it starts selling way
short after that.

The rigged pumps get busted when someone notices an obvious rip,
like the pump telling them they put 100 gallons into their motorhome
with a 95-gallon tank - and it was 1/4 full when they got there.

Yes - it's literally a one-in-a-billion plus type thing, but your
cellphone does have a little brush-type electric motor inside for the
Vibrate function, and there's mechanical contact switches behind the
keyboard that make minute little sparks when you press the keys.
Given a healthy cloud of gasoline vapors it does produce enough energy
to light them off, it does not take much.

I tell people all the time when I see it - it is NOT the law in the
US, but it's simply a good idea to back off 10 feet from the pump and
yack on the phone, or the two-way radio, or do anything with any
battery operated device in a potentially flammable atmosphere. And
don't take any active moves like answering or hanging up a call when
right next to the nozzle. A tiny little bit of paranoia can be
healthier for you.

Think about it. One in a billion is really good odds - unless
you're the one, then it sucks. Let someone else be the one. ;-)

They do make a few phones and two-way radios that are FM rated for
Type 1 Division 1 Explosive Atmospheres, but they ain't cheap. The
refineries and fuel distribution tank farms buy them for use on the
grounds, nobody else bothers.

There's more hazard from getting back in the car while the gas
pumps, because you can build up a serious static electricity charge on
your clothes. A healthy static ZAP from your hand to the dispenser
nozzle on a very dry day can be enough to light off the fumes. That
is not a one in a billion, that's somewhere down in the low millions.

Actually, I had c-sections, so it was never dilated.

Just one more thing that adds to the price of gas at the pump.
