Just another linguistic irritation:
Why do people add "at all" to their questions? e.g. "Is Bob there at all?" ("Well, he's here a little bit...") "Do you need a bag at all?" ("Well, just a bit of a bag, thank you")? ...and another one...(on the phone) "Who is this?" (Well, if you don't know who you are I'm not going to tell you! - did you mean "Who is that?")
