A couple of nights ago for some reason, I had this hankering for either a Whopper at Burger King or a Big and Tasty at McDonalds. I decided to go to McDonalds. Ordered my Big and Tasty, large fries and a nice big diet whatever.
I get home and after eating half of my Big and Tasty, I notice that there is no meat

First, how do they make the mistake of making a hamburger without any meat and next, are they really that bad that I didn't notice there was no meat until 1/2 way through it?
