Yes. Whether it's rewarding or profitable or safe will vary wildly with where and when and who knows what. There may also be license requirements and in some places you'll need to drive a truck or something professionally before you are allowed to drive a bus. And any work with children may have extra requirements. Either way, it's customer service and a lot of techs consider that the most stressful thing there is.

Worth looking into, though, if there's any chance you might like it.

Edit: Oh, and traffic! I hate traffic. I can't imagine having to pilot a bus in traffic. I don't know how I forgot to mention that.
