The Next Time
If you watch soccer regularly you've probably witnessed this situation many times: the referee calls a penalty kick against one of the teams. Immediately, the players of the affected team surround the referee, yelling and gesturing in protest, keeping at it for enough time to make the referee uncomfortable.
Now, if you watch soccer you also probably know that a referee never takes back a penalty call. So, why do players bother to protest if the outcome is not going to change? Because they're trying to condition the referee to be more lenient on future calls. They're not thinking about now. They're thinking about the next time. If somebody you do business with on a regular basis screws up and there's nothing they can do to fix it, you still need to complain. Not to vent or try to change what can't be changed, but because you're already negotiating for a better deal next time. Image credits: Tony Austin
