That if you like, er, and I've used this example before but I'll use it again, it was quite interesting I think anyway, is that one of the examples we used  on one of courses, is that somebody calls into the depot and says, I need help, I've got to get this delivered by tomorrow and collections or you or whoever takes the call, is very excited because this person says it's three hundred and fifty kilos and I need it today, it's Durham, we'll use Durham, we're starting from here, in Durham tomorrow morning.
