All Caps

I hate when people write in all CAPS. To me it is like shouting. My husband does this and so does my receptionist. No matter how many times I ask them to write correctly, they do not. When I use their computers and start to write a sentence it begins lIKE tHIS, because I naturally start of with a capital letter but the computer is in cap lock. I have sometimes written a few lines before I reread it only to find tHAT iT lOOKS lIKE tHIS. Then I have to go back and rewrite. My receptionist enters data in all caps and then we have to redo it so it fits the report format. Why can't people listen to instructions?
