2 out of 3 ain't bad and it's all you're getting

In this business, and especially at times like this (recession! doom! gloom!), clients tend to demand three things from an agency.

Work that is...

Good.
Cheap.
And turned around quickly.

The trouble is, it just doesn't work like that.

If it's good and delivered quickly, chances are it won't be cheap.
If it's cheap and quick, chances are it won't be any good.
And if it's good and also cheap, it probably took some time.

But of course, that doesn't stop them from asking.
