Bribery involves offering or accepting something of value in a situation where the person who accepts the bribe is expected to perform a service which goes beyond his or her normal job description. For example, a motorist being ticketed for parking in the wrong place might offer a bribe to the police officer to ask him or her to tear up the ticket. In many regions of the world, bribery is considered a crime, and it can be severely punished. In other areas, bribery is more socially acceptable, which can place a heavy burden on those in the lower ranks of society, as they cannot afford to bribe officials in the style to which they are accustomed.
Any number of things can be used as a bribe. While money is a classic bribe, bribes can also be more intangible, and they might include things like offers of real estate, valuable objects, or a promise to perform a particular service in the future. In order to be considered a bribe, the object of value must be offered and accepted with the understanding that the person who accepts the bribe will be doing something in return. This differentiates bribes from gifts offered in genuine good will, and also distinguishes bribery from tipping, a practice in which gifts are offered in return for good service.
