Notice the difference? Might want to try picking up a dictionary every now and then so you don't get confused by dramatically dissimilar terms...
Hey there Captain Literacy, I said consumers,
NOT YOU is what counts. I've had plenty of customers that take "it'll be done at 6" as "call me at 4 because it should be done".
