A young man in a gray shirt hovers over his beer bottle and Guinness glass pulling green things out of his beard.
The gentleman in the t-shirt really shouldn't drink so much beer, as now he has little green pieces of something in his beard.
Not all gray shirts are t-shirts; just because a man has green things in his beard doesn't mean he drank too much beer or shouldn't drink a particular amount; we don't know whether he has even begun drinking, or whether he put the green things in his beard in the first place.
Just because a man is pulling green things out of his beard doesn't mean he shouldn't drink so much beer.
