This is a story from many years ago, before seat allocation in movie threatres.
I arrived at the cinema early with my school aged daughter, to see one of The Lord of the Rings movies. We picked the best seats, up towards the back and in the centre. The cinema was not very full, with whole rows empty.
Usually you do not really interact with strangers at the cinema, everyone tends to be quite respectful.
In comes in group of two dads with about 4 children in tow.
Entitled dad asks, " Can you both move so we can sit there?" Not an excuse me, or please or any reasoning.
I reply, "No".
He continues rather more aggressively, "You can sit somewhere else."
Not sure what this guy's issue was.
I reply again, "No I arrived here early to get good seats." I can't believe I have to deal with this nonsense and I am not going to be bullied in front of my daughter.
The guy looks like he is about to have a fit when his friend starts physically pulling him away and placating him. At least one of them was a reasonable fellow, though no apology for the rude behaviour.
Luckily that was the end of it.
