ufff... almoust done...
I can compile the code but it doesn't want to work, juz like the 
variable q isn't seen properly, something with the 'case' instruction 
maybe?
(BTW sorry for Polish texts)

class Napoj

   def initialize (cen, ile, nn)
     @cena=cen
       @ilosc=ile
       @nazwa=nn
       @kupione=0
     end

    def wydajreszte(x)
          @ilosc-=1
          @kupione+=1
          return x-cena
    end
   def ilosci() return ilosc end
   def cenaa() return cena end
   def kupno() return kupione end
   def czyjest()
        if ilosc==0 then
        return false
        else return true
          end
                 end
   def nazwaa() puts nazwa end

end
class Automat

  def initialize (pie, dwa, jed, piec, dwad, dzi)
    @tab = [[pie, dwa, jed, piec, dwad, dzi],[5,2,1,0.5,0.2,0.1]]
         end
   def monety(n, s, g)
         x=s-n[g].cena
