Caffene deprived

It's hard not the be Jewish in Jerusalem.  The Sabbath brought a whole new level of reality to these pilgrims, including elevators in our hotel which stopped at every floor without even as much as a button on it's floor indicator pannel being punched (too much work for the Sabbath).  For caffene adicts, Sabbath is a real challenge because it's forbidden to boil water.

How do non-Jews survive?
