I think you need to change your class of restaurants. Sure, the scrambled eggs, are quite common to be made with sweetened condensed milk in Thailand. Only the better hotel breakfasts and higher class or more expensive restaurants will use the right stuff.
But, the french fries??? I just wonder how low you have to go to find a place where they sprinkle sugar on them? I know that they are sometimes not using salt, but never senn any sugar on french fries.
