Me: "Yep, we do template driven websites."
Customer: "What does that mean?"
Me: "Well it's a set of preconfigured templates that you add content to. The only restriction is lets say you want a bumble bee floating in from the left, that's not going to happen."
Customer: "That sounds perfect."
Four days later.
Customer: "Hi Pete, I'd like to go ahead with that site. You know you was saying about it being template driven, what if I wanted a speech bubble?"
Colleague: "Ah well, see Pete, you told him about the bumble bee but you made no mention of speech bubbles did you?"
