A funny quote from a client (not a client of mine):
I’ve decided that the amount you invoiced us for is far too much. Here’s my thinking: We are paying you to come up with an idea– we’re not paying you for the time you take to think about it. The actual idea must only take about 30 seconds to think about as you come up with it. All these visuals, that’s just typing. I can do that in Word. It would take me 5 minutes. So I only want to pay you for 5 and a half minutes work.
