How can I sound more important?

I'm pretty sure this is becoming more common, or at least I have heard it more: the practice of substituting 'me' with 'myself', and 'you' with 'yourself' as in 'If you could send that to myself please' or 'We can book yourselves in for this weekend'. I can only assume that people who do not understand the English language think it sounds official in some way, or that terror of misusing 'I' or 'me' somehow leads people to thinking that misuse of the reflexive is preferable and will always be considered at least right-ish no matter what the circumstance. Either way, it grates - I would rather hear someone confuse 'I' and 'me' than complicate a sentence with unecessary use of 'myself' or 'yourself'.
