I see it time and time again. Players jump up and down complaining about an umpiring decision, trying to convince the umpire or referee to change their mind. In years of watching many different sports at many levels, I see the same behaviour and maybe once or twice have I ever seen what appears to be an umpire who has reversed a decision, which may or may not have been influenced by the player. Players will always think that they are hard done by. I really admire a sportsperson who will get up and continue with the game despite an obvious penalty being missed by the umpire. The umpires will not always get it right, but I think they are always trying their best, as do the players.
