hahaha, that kid in the fairy costume is hilarious! I'd never call off work for false reasons, so I think what I or others do in their freetime should be ok. If he had gotten off work with a vacation day and had that photo on his facebook, I think he should have been fine. It was the fact that he lied and got caught... not that he drinks....
The fairy costume was not a good idea though. Irish people don't like fairies.
