Here was that work in progress for the strings and cases stuff we did earlier...

gistfile1.rb

print "Hello, what is your name ? > "
first_name = gets.strip.chomp
puts "Hello #{first_name}"

# Do the same thing for the second name
print "Ok, what is your second name ? >"
last_name = gets.strip.chomp
puts "Your full name is : #{first_name} #{last_name}"

# Ask the user for their age, and say that they can't come
# in if they are less than 21 years old...
print "Er... how old are you? "
age = gets.strip.chomp.to_i

unless age < 21
  # Give them a choices of drink, and depending on which 
  # drink they choose, return the % proof in their bloodstream.
  print "What's your poison? "
  drink = gets.strip.chomp

  case drink
    when "stella"
      percent = 5
    when "rioja"
      percent = 14
    when "whisky"
      percent = 40
    else 
      puts "Sorry we're fresh out of that..."
  end

  puts "Woah, thats #{percent}%..."
else
  puts "You're too young to drink..."
end
