Doc says's to the replicator : Duka Tea hot http://www.startrek.com/startrek/view/library/food/index.html
Then sits at the very last table in the Mess.... She sips her tea, Thinking over all her duties on her next shift....
Tea, Hot
at that moment a cup of tea materializes on the replicator pad and Niles picks it up and goes off to take a seat among the various seats in the Messhall
"Hmm."
Looks to see if there was anyone to talk to.
There wasn't sadly, so he sat sat down near one of the few windows in the messhall.
