Me - so how many do you need?
Customer - I'm not sure
Me - ok, so what should I quote you?
Customer - what is the cost per piece?
Me - it depends on the qty
Customer - how much is just one?
Me - it is $$$$$
Customer - wow, that's expensive! I'm going to need at least a dozen, that will be way over budget
Me - well at 12 pieces, they will be $$
Customer - why didn't you tell me that in the first place?
Me - sigh........
