Only a writer in the guardian could possibly describe conning your way past a massive queue of people who are doing it the proper way, or running past people who are clearly moving towards a table to take it, as 'just spirited'.
What an awful woman.
The article is in general totally idiotic. It seems to be premised on the view that, because there are worse kinds of rude behaviour, the kinds she engages in don't matter.
The same goes for the phone comments. She tries to justify her 'glancing at her phone during the course of a three hour meal' (which I'd be willing to bet means she sits there texting during much shorter meals) on the basis that it's not the 'end of decorum'. That is completely stupid. It just doesn't follow.
The article reads as though it was written a woman who, really, knows she's acting badly, but feels she has the right not to be made to feel bad for it. I bet she sits at dinner tables texting, ignoring the people she's supposed to be there with and paying attention too, and gets all hissy when she gets a look for it. If she had backbone she'd at least accept the fact that people might have legitimate reason to comment on her behaviour, but she can't even do that.
So, in summary, I think she's pathetic, awful, and stupid.
