It's all priorities and circumstances though isn't it?
DP and I earn quite a bit, but depending on where you met us, you might know it or you might not. We have lovely holidays and when we eat out, we tend to push the boat out (except for the odd Nandos before the pictures!), but we don't do it very often and don't run up credit.
We have a Cineworld card and a gym membership. We have no DC so all of these things compliment each other - we can go out regularly, to the same area (very near where we both work) for not a lot of money. £15 a month each for Cineworld, but if we sit in on a Friday night and have a G&T, then some wine, we could knock back more than that of an evening.
For us, these things make sense and allow us to do positive things of an evening rather than veg / wine / chocolate and boredom (which I can easily fall into). It's also a great way of ensuring we schedule time together, because at least once a week we do gym + healthyish dinner + cinema together (we do them separately as well). To offset this, I tend to take packed lunches, try to minimise commuting costs and almost never buy posh coffee.
Having said all that, we are technically high earners (though I feel comfortable, but by no means rich).
