Just an aside. You’re getting a really polarised view of everything with this post.
So many people can’t comprehend how anyone can spend £20 on a cocktail. When I go out, I drink cocktails and the price depends on the venue but £12 is comparatively cheap, £18/19 is about what I would normally pay.
Whether this is truly mind blowing and appalling is more to do with what they’re used to. My kids wouldn’t bat an eyelid at £20 cocktails because they, by adulthood, will have had over a decade of watching me order them without batting an eyelid.
It would be pretty crappy of me to then, in a couple of years time, sit utterly appalled at them ordering the same drinks as I’ve ordered all along. I don’t sit and say how expensive my drink is or what a treat it is to be here so why would it feel like that to them?
If your kids have been used to dining in similar places, don’t judge them - they’re a product of the upbringing you’ve given them, for good or for bad!
I doubt they can actually comprehend the impact on all of your lifestyles that these changes will bring. If we divorced, we would absolutely have to both change our standard of living. But I would have to do that while being sensitive to the fact it would be a huge change to the children and all they know.
Kids are largely a product of their upbringing - if you don’t like what you’re seeing, you also need to look at yourself too.
