so at gas stations they always have signs that say “avoid spills insert fuel nozzle correctly”. I always wondered why would anyone stick it in upside down, until the other day I actually saw someone do it. Is there any reason for going through the extra effort to flip it upside down, and how bad is it really?
Probably for the same reason you see these signs around -

You can see such signs in Germany
On some very old cars there is an external vent on the upper end of fuel filler pipe that vents to atmosphere. With modern gas pumps, especially those with a "collar" around the nozzle for emissions, it can be necessary to angle the nozzle to prevent gas from splashing into the vent and spewing onto the ground. (Image from 1965 Rambler shop manual.)

never seen it
I think people might turn the nozzle sideways or upside down when the pump keeps shutting off too often during filling for some weird reason on some cars. Heard that it supposed to disable automatic "shut off valve" on the nozzle but never tried it myself since disabling automatic shut off might overfill the gas tank and eventually damage EVAP system.

I didn't know you could put the nozzle in more than one way. Based on the dimensions of the thing (the nozzle points downwards when pumping gas, flipping it would spray it at you). As far as I knew, there is only one way to do it.
I guess, theoretically, it could be done if you're that dumb. All the mechanics of pumping gas practically requires you to pump the gas normally. There's a handle inside the pumping apparatus that you must either hold down awkwardly, or or you can attempt to pump it with the auto shutoff. Somebody would be asking for trouble, if you can actually do it.
This is purely anecdotal. I’ve never done upside done, but I have done slightly sideways. For some reason, some pumps at some stations automatically shut off way too easily, and by tilting slightly sideways, it can still flow but stops when full. Either that or don’t pump as fast.
I would guess that similar logic is used for upside down, but that is just a guess. I don’t necessarily recommend upside down.
