Customer: "When can you make our site live?"
Me: "Its 10.40am now if you can get it done by say 11.30am our DNS updates at 12 midday so in theory you should be live after that time"
Customer: "Groan, hm, erm, oh, OK thanks"
Huh? Do you want it live or not? Is that too quick? Would you prefer it to take a week?
