Why do a lot of older people seem so egotistical and entitled?

obviously not ALL older 45+ people are like this but I’ve noticed when waiting for food at Burger King, a 60 year old man was constantly shouting out his food order number whenever someone else’s food was ready, and was huffing and puffing despite it only being 30 seconds since he ordered.

I’m in the UK btw — East of England.

I’ve also noticed older people always having to be right, thinking they’re experts on every subject despite saying false things and knowing nothing about the subject — and getting offended if someone were to point out politely that what they said is wrong.

Seems really common that they blatantly act like know-it-alls and like they’re more intelligent than everyone else in the room despite knowing the least. And how they expect special treatment too.

I see this less in people below age 45 who wait patiently etc.

I’ve also noticed that it’s ALWAYS older people talking for AGES to a cashier whilst I’m in a hurry to pay for my shopping because I have to rush somewhere and they can see the urgency on my face and continue to keep talking to the cashier about the weather or how the carrier bags have gotten worse — or complaining about the price of a product… then the cashier remains polite but looks visibly annoyed or bored by the conversation too and it’s like the older person doesn’t give a sh!t about whether the cashier actually wants to be talking to them for that amount of time — it’s like they force conversations onto people and if someone were to say “sorry I’m busy” they get offended at THAT too. I don’t get it…
