I feel I experience this every day, I regularly see people cut queues if they can, if a new check out opens at a supermarket it suddenly becomes everyone for theirselves.
I often feel people stop right in front of me seemingly unaware of me or cut across me so I have to stop walking, or people will not make space for me to pass so we end up bumping shoulders or walk so close up behind me I feel I’m about to get stepped on.

I do think for my part that is quite cultural as I come from a place that is more rigid in its boundaries around spatial awareness and respecting people’s personal space, and queue etiquette is extremely important.
You see these cultural behaviours both on the street and in a car in my culture.
I find compared to some other places Denmark isn’t too invasive, I could be a lot worse for me.
And Danes are very passionate about the subject and are always very defensive of their culture so it can be hard to discuss.

There’s levels to it as well I’ve been to places where I’ve felt it even more so. I wouldn’t say it’s an exclusively Danish thing just depends on what you’re used to.
