It was hardly the first time Greg Powers had been approached on the street by someone who knew he was a doctor, or worked in the ER. Usually it was something they weren't sure they should bother their usual doctor with -- almost always, if they were nervous enough to ask a comparative stranger, the answer was yes -- and a few memorable times he'd had desperate people try to mug him for medications he most certainly didn't carry around.
This time, he grinned at the werewolf who'd dropped into step beside him and asked teasingly, "Tetanus booster or rabies inoculation?"
Oz winced a little. "Advice. I'm losing nights that aren't full moon."
"Ah." Gregor studied him, noticing the start of circles under his eyes. "Coffee. Then research."
Oz just nodded. "I'll buy."
