You arrive at the puzzle location and are greeted not only by a piece 
of paper with a puzzle on it, but also a bartender with ten bottles.  
You are told that the bartender will pour you any mixed drink you ask 
for.  If you request and consume a drink that the bartender approves 
of, he may give you something of value.  Guessing will be discouraged 
by the fact that some of the bottles contain things that taste gross.
