2. Dice Inspector
Gambling is a big business and dices are rolling all around the world. If dice angle is imperfect or the dice has incorrect proportions or if it has slightly distorted centre of mass, dice will favour one outcome, therefore corrupting a game of hazard. Moreover, a company which produced and delivered corrupted dices could be sued right away. For this reason, a dice inspector has to check every dice very carefully which is indeed a tiring and a time-consuming job. I bet you would not like to do it.
