Jazz was on her way to Michaels Bros. to attempt a half-day - attempt, because she doubted her own ability to stay focused on spreadsheets and productivity reports when the biggest percentage of her mind was away with Tom - when she recognized Drew ahead of her in line.
For a moment the scrubs confused her and she wondered if she was more tired than she thought and in some sort of waking dream where she was actually still at the hospital...but then she heard Joy say something rude to the customer she was waiting on and she knew she was awake.
She'd never dream about Joy, she got enough of her while she was awake. Her subconscious wouldn't be that cruel.
