Boss: The users are typing wrong info in that text box. We have to automate and lock it
Programmer: Okay... We can do this, but there are some situations when the user has to type the information, due external unpredictable factors they don't fit in the rules
Boss: So, you can do this way: Create a unlocked field where the user can type what he wants, but, at the same time, it's locked to prevent him to type wrong information
