Is it wrong to buy myself a small treat as a reward for working hard?

I F25 recently found work, I bought something to spoil my family, even though I don't like wasting money on dumb unnecessary things, I grinded on this job and I worked long hours. I wanted to buy a burger to thank myself. Even for something this small, I need outside perspective. Thank you.
