The word "coke" meaning all sodas actually has a funny story too it. A while back, the USPTO started threatening that Coca-Cola could to lose their trademark on the word "coke". It turned out that in most places when you ordered "coke", you would get Pepsi or Coke or whatever brand that place happened to have. Since the word was passing into the common usage, Coke would lose their trademark. Similar to what happened to Xerox, Scotch, and Jet-Ski. Coke mounted a huge campaign against this. If they got wind of a restaurant doing this, they would threaten to sue, and would write very threatening letters. This campaign was very successful. That's why now you should always get the "Pepsi okay?" whenever you order a coke and all they have is Pepsi.
