Select Entire Sheet and Delete all Cells Except Column A

No - I've attached the simple spreadsheet. Column A will never change so they want to use this as a template and for the person to be able to select the entire sheet or select all rows and hit the keyboard delete button and have only column A intact. I don't understand why they can't just select column B and highlight over and delete, but for some reason they would like to be able to do it like the way I described. I have ASAP Utilities and thought it would be a simple process but I can't find anything to help me isolate that one column the way they want.
