If you're going to book a tour on a bus, do it inside one of those tour centers ahead of time, where you can pay with a credit card and be assured that you know what you're getting and that you will not be ripped off.
At least when you pay with a credit card, if you end up getting cheated somehow, you have an easy way to dispute it. If you hand out cash to someone, you have no guarantee of anything whatsoever.
