Why are airport alcoholics so repulsive?

Question

You know when they are near because of that raunchy fruity odor they have. Why is it so repulsive particularly in an airport/airplane setting?

Answer 1

Cause the air is stagnant. It's even worse when they have the aisle seat and beer farts.

Answer 2

The airport is the 3rd most frequent place you find drunks, following close behind bars and Catholic picnics.  Plus that refiltered air just makes the smell worse.
