Vodka has been called the drink of choice for "secret drinkers".

Apparently it's hard to detect on your breath, so you can take a shot at work and your coworkers won't be the wiser.

If so, I can see why they both are so good at it...

Since vodka is hard to detect on your breath, your co-workers don't think you're drunk, just stupid.
