My parents were in town and like to treat to expensive dinners. I don't think there is anything wrong with it. They have the money and that's how they like to spend it.
We went to a bar/restaurant with a great view, but limited food menu. One of the cheapest options was a hamburger with fries for $24. My wife and I really enjoy hamburgers, so that's what we ordered. Unfortunately, it ended up not being that good.
We joke that our old college bar has better burgers and they still sell for $7.99 with fries. One night a week, they have 2 for 1 burgers, so that's only $4. They also have $2 micro-beer pints on tap, instead of $7 pints. It was our 3rd date about 8 years ago. We are making plans to make a special trip back.
