See I made a mistake and wrote "Do we go to go?" instead of "Do we go to grammar?"It is a typing mistake. What is the result of my carelessness? A well versed friend like Leon is not able to understand a very simple and easy sentence. A silly mistake can't have more devastating effects.
I ,however, could understand what you mean by 'wrogn'. Some people may feel confused and fail to understand!
The same is true of the 'customer-waiter' sentence. You have been able to understand the meaning but does your understanding make the sentence appropriate and grammatically, semantically acceptable. The sentence continues to be unacceptable due to a flaw which is not easy to detect but very common, at least, with students.
My second example proves my point. It needs to be examined. It is not “THEM" as you think. Let's not close it here.
I think we should look at things from the point of view of students. You and I can understand things which are extremely hard for students.
Could you elaborate upon the “three counts", please? ,which help in deciphering the meaning of the 'customer - waiter' example.
I could make it to two , that too after a lot of pulling and dragging.
