His area of expertise, what he studied at university for several years and put into practice for several more before moving up the work ladder, is now largely redundant as he spends most of his time dealing with complaints from co-workers.

Who parked in the wrong car spot, who borrowed a piece of equipment without asking, whose smelly sandwich is in the fridge. 

There is the suggestion that complaining evolved from humans’ innate desire to warn companions of problems and dangers.

Where once that might have been a sabre tooth tiger, now it’s who left their coffee cup in the communal sink.

While most people believe complaining actual adds to someone’s stress levels, some psychologists believe the venting can improve a person’s wellbeing depending on the type of whine.

For example, complaining about something as a means to effect change is counter-productive and usually increases stress when nothing changes.

The “why doesn’t somebody do something” whinge. 

However, complaining to a friend or work colleague to get an empathetic ear can be of benefit if they agree with you and offer some positive feedback to your negativity.

So in the interest of good mental health, here are some of my biggest gripes, which I hope you will agree with.

ATM users who cannot use ATMs: Seriously, how many times have you got stuck behind someone who cannot remember their PIN and punch random numbers into the keypad before hitting the cancel button and starting again.

There should seriously be an ATM for people who can quickly and efficiently withdraw money and those who are better off keeping the cash under their pillow.

​

Surprised shoppers: The same mentality seems to apply for people in the supermarket checkout who are genuinely surprised by the whole exchange of money for goods.

After waiting for the poor 10 items or less checkout operator to scan their basket of 20-plus things, they are overwhelmingly shocked that they have to pay for them and only then begin fumbling around for some form a currency and find … a cheque, perfect!

Footpath hogs: That group of people who walk three abreast along footpaths, blocking the whole area for oncoming pedestrians.

That’s fine, I’ll walk on the road because you’re too inconsiderate to tuck in behind your friend for one second.

The same goes for groups of dawdlers when you’re trying to overtake.

Move aside people, I have 30 seconds for lunch. 

Distracted walkers: I don’t understand people who walk in one direction while looking in the other, usually at something in a shop window. 

Society would simply fall apart if everyone did this.

If you want to look at something in a shop, please do so, but walk towards it. 

Same goes for people texting and walking. I’d like to whip out my own phone and pretend to be as equally distracted so I could deliver an accidental Tony Abbott-style shirt-front. 

Loud talkers: You know the person yelling into their mobile phone in public like they think that increasing the volume of their voice is the only way for it to reach the person on the other end.

Tone down the decibels please. And don’t get me started on people who whip out their phone in the cinema.

The sad little vignette at the start of the animated movie Up was destroyed by someone a few rows back having a 10-minute chat.

Feel better now?
