people taste the layers in a sandwich or a hamburger.
I think it may have been McDonalds or Burger King.
The order of the toppings is done in such a way that they
hit our taste buds in the most palatable way.
I know I have a certain order preference for my sandwiches
and hamburgers. I'm sure most everyone does.
For me, the meat and cheese need to be together.
Always extra mayo, which is on the opposite end of the
sandwich from the meat and it needs to be touching the lettuce.
Tomato and any other toppings can be in the middle.
If it's a burger, onion and ketchup go under the meat.
cheese, tomato and anything else goes on top of the meat.
LOL! I know, I'm complicated. But I bet you have
a few preferences yourself, don't you?
