Ash deciding to play along with his hallucination started to reach out to shake her hand but then realized he had his chainsaw attachment on.
"Oops." He stated and then looking around he spotted what looked like an umbrella stand next to the sign about no violence or weapons inside the cafe.
Since this was all a concussion induced dream, Ash shrugged and dumped his shotgun into the stand. Now that his last good hand was freed from the weapon he reached over and twisted the chainsaw till it popped off with a click. Reaching into a leather satchel hanging from his neck he pulled his mechanical hand out and twisted it into place. Flexing his fingers to make sure everything was working correctly he then reached out took the waitresses hand and bent his head to kiss her hand.
"Ash Williams at your service. And I must say so far you are he prettiest part of this concussion."
