i am no doubt projecting wildly.
I just know what I'd think if someone said we're going out and - what was it? "we are eating here and watching this."
I'd think whoa, buster. Hold up. Is that an invitation or a command
but I'd probably nod politely
and say ok, thinking I was going along with what everyone wanted to do.
So it isn't impossible to me that her friends could see it as controlling and individually not had the guts to say no, or each thought everyone else had ageed to it and so said yes but then all got together and said were you ok with that? no, not really, I wish she'd asked what I wanted. Me too, I would have liked to have seen X not Y, yeah, I wasn't bothered about Y but I don't really like A food, me neither, but it was like - this is what we're doing... well, what would you like to see? why don't we say that? we can go to eat at that other place instead...
Of course, they could all be like my mum, who can't make any sort of decision whatsoever, not even choose what type of biscuit to have and dithers for so long that I am seriously considering leaping across the table and beating her to death with the biscuit barrel 
I think it was the 'we ARE eating here and we ARE watching this' and that they agreed to it, that made me think less agreed between all of them and more decided for them. iyswim.
Yes, it was rude of them to spring it on her, they should have just said at the time that they'd like to all decide together, but I do think from what was described, that it is possible that they saw it as dictatorial.
But, I may very well be totally wrong. It's just an interpretation of a few sentences.
from which I seem to have developed some sort of screen play
