Not really tin-foil hat stuff, but
I have little mantras that I repeat to myself when I do certain tasks. For instance, when I am carrying the cat bowl full of water, or a full cup of tea, I routinely repeat "don't drop it, don't drop it, don't drop it" in my head.

When I am driving up to the pumps at the petrol station I have to say "driver's side, driver's side, driver's side" to remind me which side of my car the petrol cap is on (but I suspect I do this more to avoid looking like a twat if I park on the wrong side).

When dining out at that fine eating establishment, MacDonald's, I always, ALWAYS, dunk my fries into my chocolate milkshake.

At bedtime, my OH always gets a back rub because I like finding any spots and squeezing them.

And I won't smile after I've eaten until I have checked that there is nothing sticking in between my teeth.

That Drivers Side thing
I pull up to the nearest empty slot whichever side it is. All the pumps reach to both sides these days and so I have an edge over people like you who halve their options.

I never once considered the possibility that other drivers thought I was a numpty who didn't remember which side the petrol cap was. If they do then more fool them.

Ha!
Look at that idiot, driving quickly past me and filling up his car while I'm sat here waiting patiently! He looks like such an idiot, filling his car from the wrong side! Honestly, some people today- it's like an idiocracy or something.

Look at him, driving off! Joke's on you, buddy- the car at MY pump's just about finished buying his week's worth of shopping. If he was a sensible, right minded person like me, he'd be over there queuing behind that old guy in the Agila on the other side of his pump.

Some people, eh?

I used to do this...
I even convinced the now ex that she should do this too until one day we were driving through the arse end of nowhere and she had to fill her car at a small town garage. She takes the hose to the far side of the car, it doesn't have much give, she ends up squeezing the handle and gets covered in petrol. I giggled uncontrollably for a while and have always used the "correct" side pumps since.

In most cars
if you look at the fuel guage, the side of the petrol pump Icon that has the hose is the side that the filler is on. Some have a little arrow.

This probably isn't 100% accurate, but I have never had a car where it wasn't thus.

Yeah, I know this is all true
but this is my OCD thing. It never looks odd to me when other people just fill up whatever side they park and I even think - "why didn't I do that?" - but then I can't do it because I think other people will think I'm a div.

Never realised about the little fuel gauge icon - will be compelled to check when I'm next in the car.
