Office Users
My experience with most office users, including the macro lovers, is they have very little knowledge about computers. On occasion I get to "debug" that in some Excel spreadsheet the date format is wrong when it is loaded from a csv file. Excel has its own ideas about these formats. After running the first of these down, I told my boss I will not write a macro to "fix" the problem since this would get users in the habit of running macros in Excel. My boss agreed and we have solution, just tell the complainer it is an MS failure that we can not fix. It seems to work.
