Drug Testing

My office is very relaxed. We've had pajama day, okay?
But only a moment ago, a senior administrator walked around and asked everyone what they enjoyed drinking. A friend joked that he only smoked and snorted.
After she left I couldn't help but wonder if that's my company's way of drug screening.

*in all actuality, there was left over liquor from happy hour last week and she surprised us by bringing some drinks to our desks.
