The ball boy has got his 5 minutes of fame, he will no doubt get some sort of compensation even though he wasn't doing his job properly.
Frustration boils over and when it was so obvious what was happening with time wasting then players may react. You can't do what Hazard did and he will get banned for it but this incident will now happen at every ground in the country, guaranteed!
If I wasn't dong my job properly, I would be fired or disciplined, it wouldn't be forgotten about if someone did something else that is perceived to be worse.
