Depends on quality. Shitty takeaway pizza like dominos which I hate, yes. Nice pizza with interesting toppings in a lovely setting with good service and no washing up, yes.
Coffee can be but again on a sunny day a drink outside a nice cafe/coffee shop and watching the world go by is worth it vs a very nice coffee from our kitchen (though my husband does know his way around the espresso machine/milk steamer!)
It's about priorities for us. If I didn't have enough money to have a takeaway several times a month and go on holiday, I'd rather go away. Others prefer treats smattered across the year. Ditto some people won't be able to save for a deposit for years because they're enjoying youth and travel, constant socialising and nice things. That's fine too. I don't think there's a right or wrong answer.
