Dining out, delivery, take-out. It literally, in basic terms, is a waste of money. I can clearly save money buying groceries in bulk and planning meals and cooking at home. Probably would be healthier too!
But I can afford to do it, I enjoy the variety and fun of dining out/etc, and it saves me a lot of free time I don’t want to put into cooking. So I will certainly continue to do it sometimes.
My time has a monetary value too. Especially my free time, there is utility there. So I find it worth it, for me.
