Some moons ago, I was engaged in a protracted debate with TalkTalk. This finally came to an end with a message on my answering machine where a very officious woman admitted they'd stuffed up. My joy was marred, however, by her persistent use of phrases such as "our service to yourself" "we have credited yourself" etc etc.
I hear it all the time - the really quite fab junior rally driver interviewed on PM the other night. Lovely chap, but the misuse of reflexive pronouns made my teeth itch.
Why do people do this? My only thought is that it's somehow seen as a more formal form, somehow, and that it's some weird hyper-correction. Anyone have any other ideas?
