Airport queues are enough to test anyone's patience. We all expect a certain airport etiquette when it comes to lining up patiently.
This means respect for the queue at all costs, and no pushing in. That's a real no no. If anything is going to rile people, it's those who think they don't have to spend hours queuing up while the rest of us do.
But sometimes 'queue breakers' push their luck and tempers can get heated. One woman has shared her airport account on Reddit, where she admits getting hot-headed when fellow passengers pushed in.
After a long flight, she was eager to get her luggage and head home. It would have been a smooth run if everyone had behaved themselves, but it was not to be.

"Just got my bags after a 13 hour flight," she said, "and was lined up to walk out of the baggage claim area when a 'Karen' and her husband pretends not to see me and cuts in front of me."
This annoying encounter escalates: "I tell her, 'hey, if you didn’t know, the line starts back there,' and she immediately begins to mock me by mimicking what I had just said and sweeps her arm to allow me to go in front of her (lol).
"So, I did. Then, she spends the next five minutes continuously mocking me while I can hear everything."
Everyone is tired and wretched after a long flight, but is this seriously the way to behave she wonders?
"I'd just about had enough when I turned around and looked at her and said, 'excuse you', and she looked at me and finally stopped. Probably just started mumbling under her breath or didn’t expect me to actually turn around and say something."
She was pleased that she managed to hold her tongue and stay calm, but the woman's attitude 'really tested' her patience.
"I had many choice words that day, but I didn’t fancy starting a fight where border security was right there."
The response to her post was broadly supportive, as many others shared similar airport situations and difficult passengers.
One person said: "You asserted yourself and she showed her pettiness by being unable to acknowledge being in the wrong like an adult. You were right not to escalate things; she and her enabler weren't worth it."
Someone else had a different suggestion: "You should have played it cool. I would have said, 'Yo honey, haven’t see you in a while, how have you been?' In front of her husband.
Let them fight it out, and if she claimed that she doesn’t know you. Public shame them by calling them out for cutting you."
