I don't agree that it is a sad reflection on society at all. It was a table in a restaurant, not someone withholding the cure for cancer. No need to get too deep about it.
It wouldn't be a big deal to most people that they can't sit right by their friends in a restaurant. Or, if it was a big deal, they would have booked a large table, if that was allowed during covid?
So, it wasnt a big enough deal for them to sort it themselves beforehand (minor inconvenience to them), why is it expected that the op should have the inconvenience of moving, minor as it was? If the benefit is only for one party and the other party is the one being inconvenienced, it is fair enough for them to say no. Add to that the inconvenience to the restaurant, as outlined up thread and these people who couldn't be bothered inconveniencing themselves in the slightest to accommodate their whims, are inconveniencing innocent bystanders.
So, if we really do want to get all deep and "oh what a sad world we live in, tut, tut, tut", I would direct the ire at the table for ten lot, personally.
And virtue signalling is rife on MN. All the I'm just too kind / honest / selfless to do what you would do
. It is a bit irksome and sometimes amusing. Not talking about this thread in particular, but just in response to the "to mock people who are Kinder Than You" comment.
