Why are people so impatient and nasty?

Each of those examples could have easily been avoided, you are at fault in all of them, you need to be aware of your surroundings. I obviously don’t condone people being rude but how long are we expected to wait for you to notice others around you? I am never openly rude to people oblivious of others and holding me up but it is annoying

The phrase you are looking for is ‘excuse me please’ or ‘pardon me, I just need to grab something from behind you.’

Being time poor is no excuse for appalling behaviour. You are also modelling behaviour for your kids to learn.

Can't say I've noticed this and have been driving almost every day for over 20 years

Yesterday I was in a long Q at temporary lights with the person at the front just sat there with a green light and a clear road ahead, I assume looking at their phone. It meant far fewer cars got through than should have - I bet they'd say it was "just a second" too

Have you been driving in Leeds? All drivers behind you beep within a nanosecond of the lights turning green. As experienced this myself when lived there for a few years. I have turned into a Leeds driver as usually the driver at the front of the lights are either checking their phone, or another time, a lady applying mascara.

Perhaps it’s because many people are in a hurry and get irritated with ditherers and faffers.

I know I do, whether I’m in a hurry or not. Not that I ever say anything, I will just fume internally at the ditherer/faffer who’s holding everybody else up.

But it is frustrating when someone is standing for several minutes pondering the yoghurts when you just want to grab a pot of Skyr and keep going. I've been the dawdler and the person in a hurry but I always apologise if someone irritably says 'Excuse me' and I realise I've been in a world of my own. Dawdling in busy places is just as rude and antisocial as snapping at people.

Yep. They were rude but you sound away with the fairies and a bit annoying in shops.

Probably a slightly less sympathetic response from me, but this is a bugbear of mine when out in public, at the sheer number of people who seem to have a complete lack of spatial awareness.

Ive lost count at how many times I’ve been bumped into by people ‘backing up’ with their trollers in tow, without thinking to look to see if there is anyone behind them. I’m never nasty but I’ve trained myself out of a lifetime habit of the British way of saying ‘sorry’ when it was very clearly the other person’s fault, and say a loud ‘careful!’ Instead.

Same goes for people blocking aisles, i totally get having to check a list, but that can be done somewhere not blocking access to a fridge or section of a shelf.

I do think you are maybe not being very aware of your surroundings at the moment, and agree with other posts saying that many are time poor and rushing. There is absolutely no excuse for anyone pushing and shoving, but particularly in the post office example, this is usually a task people do on their lunch break from work so I get why the person behind was visibly annoyed.

For me its the elderly that stand too close. Before covid and contactless payments, elderly people used to hover right next to me when I was entering my PIN. I asked, nicely, could they step back. They reacted like I said something very horrible to them. It was always the elderly, never the young/mid age people that did this.

First example was them.not you. The next one was a bit of both - the cashier could have shouted next please! Last one was more you.

I'm planting my arse firmly on the fence with this one - you were in the way but others could have alerted you without being so aggressive.
As a pp said if you are time poor you simply don't have the spare seconds to wait for multiple people every day.

You do seem to keep getting in the way of people.

It sounds like your behaviour is irritating people.

YABU, you need to be more aware of your surroundings.

No need for people to be so rude, but you are not totally innocent here.

I said excuse me politely to someone blocking the entire entrance (electronic gate style not the shop itself) this morning, she stood and continued to chat to her husband, I raised my voice to ask the question again and got told to calm down! I presumed she hadn't heard the first time hence the louder voice, so I suggested they didn't block the entrance in future!

I don't think people are as at 'capacity' as they make out, as they make out, more likely on their phones too much.

Taxi drivers do this all the time, beep at you if its just a second over their usual pulling away time.

I think the first example-someone standing right behind you when you’re trying to get out a trolley-is a ‘them’ problem not a ‘you’ problem. I’d had said something back to them-like ‘my goodness why on earth would anybody stand so close behind when you can see what I’m doing?’ And give them a death stare too. Fancy snapping about that !
The other stuff sounds like a ‘you’ problem though OP-you need to be more aware of your surroundings.

Seems a coincidence. Sounds like you’re a bit annoying if I’m honest!
Lots of us have busy lives and places to be and it sounds like you’re in no rush and bumble through life!

So many idiots gawping at their phones, people dawdling or just stoping in the middle of a shoping aisle talking, or watching tumble weed roll by.
Blocking doors ways, tops / bottom of escalators talking or phone gawping.
Just bloody well move!

I sometimes get frustrated with this but I wouldn't confront someone aggressively over it. So unnecessary and so obviously not constructive. What does it achieve?

Entitlement. I do however find that certain nationalities have little concept of body space. When I go to a nearby town they are literally on your shoulder when queuing. It makes me feel uncomfortable .

Lol 😂

Brilliant response, like your style Ode

I wonder if you were looking at a paper shopping list whether you would get the same reactions.
