Well, I think as just a tourist you will hardly be in a situation of being pressed for bribes. I think. (At least if you are not in Moscow: Moscow has very special reputation.) This will become problem if you start business. Or any other situation you deal extensively with bureaucracy.

Even then you most probably will not be pressed to bribe. You will meet many complicated and frustrating rules. And find that there are ways to make life easier by bribing. You will pay a bit to some guy and he will neglect some rules for you. Just don't go to the court - this can be really horrible.
