Impossible?

    - How much for taking me from here to <Place X>?
    - That would be $40.

Quality of service would involve various things, but there could be a big taxi company called Toober, for example, with a good reputation, so you could reasonably expect to receive at least decent service from their drivers, and there would be no problem.

If you were feeling more adventurous, you could opt for a small(er) provider without an established reputation, but it would cost a bit less than Toober. Most likely, there would be no problem.
