Open your eyes
I had an email from a customer about some tapes they bought from us asking if someone could give him a call as the backup drive refused to use them.
Email to Colleague: "Hi can you give Anthony a ring as the tapes he bought are not working."
Email to Me: "Telephone number?"
Email to Colleague: "Try scrolling down this email, oh look theres his number."
Perhaps I should make the call and put it through to you? And while I'm about it hold the phone to your ear?
