Things I get unreasonably angry about.

People who say 'pacific' instead of 'specific'
Misuse of 'too' & 'to', 'then ' & 'than' and 'lose' & 'loose'

whoever named the highways in Bahrain... two major ones are called "Sheikh Isa bin Salman highway" and "Sheikh Khalifa bin Salman highway" - like really, those aren't ever going to be confused by anyone at all ever lol. Shorter, less similar names would have been better....

okay this one is more hilarious than anger making, but on the subject of Bahraini highways... one's called Istaqlaal highway, pronounced is-tak-laal, (stress on the 3rd syllable) and it means "independence highway". The voice in my sat nav pronounces it "esticle", to rhyme with testicle. So instead of sounding like "independence highway" it becomes almost "testicle highway" - it makes me want to poke the eyes out of whoever programmed the sat-nav.

oh and another one, people who pronounce Bahrain as Bar-ain. It's pronounced Ba-hrain (i.e. with a h sound in the middle), and it means the two seas (Bahr = sea, ain = suffix which means two of something).... not the two bars!!!

And people who drive in the middle lane on the highway at significantly below the speed limit (like 80km/h when it's 100km/h speed limit) because they're too lazy/incompetent at driving to drive in the slow lane in case they have to overtake a vehicle going even slower than them, or change lanes to avoid slip roads where the entire lane peels off from the highway

And people who treat the highway slip road like it's a T junction, i.e. drive up to the end of it, slow down, stop, wait for a gap in the highway traffic. I don't mind these people when the roads are fairly empty as you can just get on the highway before you get to where they're sitting and waiting, but at busy times it causes a tailback on the slip road, and everyone has to slow down and it makes it harder for everyone else to get on the highway properly.

And drivers who don't know what a yellow box at a junction means. 90% of Bahrain's traffic problems would be solved overnight if people actually waited to enter the box until they can get out again.

And motorcyclists who don't wear helmets and are wearing flip-flops on their feet and then ride dangerously. I'm not even joking.

Saudi drivers. Everyone who's ever lived in Bahrain will understand what I mean about that. (I mean the typical Saudi drivers, I'm sure there are lots of Saudis who actually do know how to drive properly, but every weekend in Bahrain, the incompetent, reckless and just plain idiotic ones are the ones you notice, and they all have Saudi number plates..... oh and the same for really crazily badly parked cars too.... "look at how that car's parked!!! I bet it has Saudi plates..... oh yes, so it does.")

Me, I don't suffer from road rage ever at all ever lol *looks innocent*

Also (not traffic related this time) people who use the word "neanderthal" to mean stupid or thuggish... they weren't stupid or thugs (no more than Homo sapiens are anyway, I mean every population has its thugs and stupid people)... it makes me want to shake the person saying it by the ears and say "neanderthals had bigger brains than you!!!" (which is a scientific fact, not an insult)

Both of these! Plus people generally using the wrong word, in some cases making up a word because they don't know the correct word.

Spelling mistakes, especially on signs designed for the general public.

Unintelligent people that think they're clever.

Most of the people that work for me.

Wait time at the dmv.
USPS driver that delivers to my house is so lazy that if it doesn't fit in the mailbox; He just puts a note saying we weren't there, so we have to pick it up at the post office; even though he didn't even attempt to drop it off at the door.
