What do you think of a man that drinks beer from a bottle with a straw?

This was a first for me to see a man drinking a bottle of beer by using a straw. I have seen cans of beer stacked on each other with a plastic tube running to the mouth, I have seen a keg of beer turned up and almost downed by one person, but I have never seen a beer being consumed with a straw. Is this common place? Is this the latest fad for beer drinkers? I have drank my share of beer from cans and bottles, but I have not and never will use a straw. Question: is the use of a straw to drink beer not against the common code of ethics for beer drinkers? Who does this, anyway?
