You could have turns as in the burgers example, first the living room, then the kitchen, but as you are not waiting 🕙 for anything, just cleaning and cleaning, the turns wouldn't affect anything.

It would take the same amount of time to finish with or without turns (concurrency) and you would have done the same amount of work.

As seen in [Return a Response directly](response-directly.md){.internal-link target=_blank}, you can also override the response directly in your *path operation*, by returning it.

The same example from above, returning an `HTMLResponse`, could look like:

```Python hl_lines="2  7  19"
{!../../../docs_src/custom_response/tutorial003.py!}
```
