I use the word "perfect" a lot also. Sometimes we have customers who object to our rule that they must proof our artwork before we print. I dunno if they just don't want to waste the time, or if they are looking for a way to dump the blame of mistakes onto us instead of taking responsibility themselves to insure that they get the proper results. So when I start to recognize that they are objecting to proofing, I explain that we do that to make sure that they are 100% satisfied with the artwork because we want to make sure that their work is as "perfect" as it can be. Most of the time they will then agree to proofing it.
Sometimes they just glance at the general design and say "yea, that's good". If there is anything critical in the design, like phone numbers or names, I will then ask them if they double checked the phone numbers and the spellings of the names, more often than not they will take a second look, and really proof it. It's amazing how many times small but important details are incorrect, like phone numbers. What's even more amazing is that about half the time they gave us an incorrect name or number to begin with. And there has been times, especially with new businesses, that we just put Xes in to fill the spot where the (not yet known) phone number will be, and the customer glances at it and approves it, and then I have to ask if they have the phone number yet, and they say "no it's not been installed yet" and I have to ask them if they wish to wait until they get a phone number so that we don't print (xxx) xxx-xxxx on their items.
The number one reason that we loose sales is because we frustrate the customer by asking a lot of details, but if we don't have the details, we can't prepare their jobs or provide quotes. Just this morning I had a guy to call and tell me that he needed a sign, but he didn't know how big it was going to be, and he didn't know if it was going to be lighted, or how it was going to be attached, or even exactly where he needed to put it. He then asked me for the price. All I knew to tell him was that if he could tell us where he wanted it, I could take some measurements and look at the location to determine what type of materials we needed for it.
He then pressed me for a price range, if I had told him that it would be anywhere between $20.00 and $100,000, he would have been even more frustrated as I would have sounded like a smart arse, even though I was being honest and straight forward.
