Spicy Doritos masquerading as regular Doritos

I bought some Doritos the other day. Actually I bought two bags because they were buy 1 get 1 free. So the first bag was yummy. Then the second bag got opened. It started out yummy too. Then it got spicy. It appears that this bag is not really plain Doritos. It seems that Spicy Doritos got into a bag that's labeled regular.
