Three people decide to go out for burgers. They are either Knights, which always tell the truth, Knaves, which tell truths and lies in an alternating pattern, or Liars, which always tell lies.

They each want a burger, and want to get 4 toppings from the list of 7 (ketchup, mustard, onions, relish, tomato, cheese, lettuce) and give their order as follows:

A: I want ketchup, mustard, onions, lettuce, relish.

B: A wants tomato too, and he doesn't want mustard. I want ketchup, tomato, cheese, lettuce.

C: B doesn't want ketchup, and he doesn't want mustard. A doesn't want relish. I want mustard, tomato, cheese, lettuce.

After giving the orders to the burger cooker, he figures out what they want.(as anyone who can cook well must be really intelligent)

If all three people didn't all want a certain topping, what do the three people actually want as their four toppings on their burger?

(Note: I placed commas and periods to remind that each item/statement separated by commas is a separate statement.)

No, not really. I feel that problem "was so ridiculously easy that any idiot could figure it out in a few seconds." (This would go back into the "non-uniqueness" way of solving a such problem)

I think it would be easier if you just said "Sorry, I didn't realize that! as I did when I realized I had made a mistake, rather than go into super detail about why. I also am confused as to why you were typing while solving another problem involving jars. You seem smart enough not to insult another person while working on a puzzle. :)
