Minion: "I cant follow up some of these calls, they're asking me when the email was sent and I don't know all I can say is some time last week."
Me: "Erm, I don't see how that stops you talking to them? It's dead easy you know, just resend them it while they're on the phone. Confirm they have it and arrange to ring next week."
Minion: "Mutter, mutter, hurrumph"
I've heard it all before.
